PURPOSE: To provide a capillary for bonding which can improve the number of times of consecutive bonding to the occurrence of abnormality in wireless bonding method and wire bonding method in spite of simple structure. CONSTITUTION: It is made possible to shorten the area where the crystal structure of the wire of the section right above a ball is coarse in bonding work, enlarging the external surface of a capillary more than the reference surface area in the case where the same external surface is a smooth surface not equipped with uneven form such as a capillary, by forming grooves 11 on the external surface of the capillary 1, thereby making the external surface uneven. |
