1. A method of manufacturing a winding-type coil component which includes:
a core member having a columnar winding core portion and a pair of flange portions which is formed on both ends of the winding core portion; a pair of external electrodes formed on one flange portion and the other flange portion of the pair of flange portions; and a winding wound on the winding core portion, wherein the external electrodes are formed on regions of the one flange portion and the other flange portion near an object on which the winding-type coil component is to be mounted such that a height of the external electrodes is gradually increased in an inclined manner from opposedly facing surfaces of the one flange portion and the other flange portion to surfaces of the one flange portion and the other flange portion on a side opposite to the opposedly facing surfaces, wherein the method comprising: (a) a holding step of holding the core member by a first holding jig having a holding force for holding a plurality of the core members in a posture where an axis of the winding core portion has a predetermined angle with respect to a holding surface which is a main surface of the first holding jig on a side where the core member is held, and a region of the one flange portion where the external electrode is to be formed projects more from the holding surface of the first holding jig than the other flange portion, (b) a first electrode applying step of, by performing the step (a), applying an electrode material for forming the external electrode to the region of the one flange portion where the external electrode is to be formed by bringing the region of the one flange portion into contact with the electrode material, the region of the one flange portion where the external electrode is to be formed and which is projecting from the holding surface; (c) a rotating step of, after performing the step (b), bringing a rotating jig for rotating the core member into contact with the core member held by the first holding jig, and rotating the core member by moving the rotating jig relative to the first holding jig in a direction along a main surface of the first holding jig such that a region of the other flange portion where the external electrode is to be formed opposedly faces the first holding jig; (d) a transferring step of, after performing the step (c), transferring the core member held by the first holding jig to a second holding jig which is positioned such that the second holding jig faces the first holding jig and which has a holding force for holding the core member, and holding the core member by the second holding jig in a posture where the axis of the winding core portion has a predetermined angle with respect to a holding surface which is a main surface of the second holding jig on a side where the core member is held, and a region of the other flange portion where the external electrode is to be formed projects more from the holding surface of the second holding jig than the one flange portion, and (e) a second electrode applying step of, by performing the step (d), applying an electrode material for forming the external electrode to the region of the other flange portion where the external electrode is to be formed by bringing the region of the other flange portion into contact with the electrode material, the region of the other flange portion where the external electrode is to be formed and which is projecting from the holding surface of the second holding jig. |
