| 摘要 |
The invention relates to a chip inductor and its manufacturing method, in which an appropriate insulation is applied between adjacent linear conductors of the coil unit to prevent occurrence of short-circuit and to enhance electric characteristics, and moreover the mounting surface by the exterior unit is a flat surface, so that appropriate mounting is realized. The constitution includes a square columnar main body (1) made of an insulating material, electrode units (6) disposed at both ends of this main body (1), a coil unit (5) connected to the electrode units (6) and disposed on the outer circumference of the main body (1) between the electrode units (6), and an exterior unit (9) having this coil unit (5) coated with an insulating resin (8), in which the coil unit (5) includes linear conductors (3) and grooves (4) formed by grooving a conductor layer (2) covering the surface of the main body (1), and the insulating resin (8) is also formed in the entire inside of the grooves (4).
