Abstract:
1. A method of manufacturing an inductor, the method comprising: a lamination step of forming a laminate having a plurality of chips each including a coil body enclosed in an insulating layer and a pair of external electrodes that are connected to opposed ends of the coil body, the external electrodes being exposed from the insulating layer; a division step of dividing the laminate formed in the lamination step at a portion of each of the pair of external electrodes into chips; and a firing step of firing each chip formed in the division step; wherein the lamination step includes: repeating the first and second processes to form the plurality of chips each including the coil body formed of the conductor pattern and the viahole, and a pair of external electrodes formed of the external electrode pattern and a conductor filled in the cutout portion, wherein in the first process of the lamination step, the external electrode pattern has an elongated shape, which is shorter than half a length of the side portion, and is formed in each of two corner portions of one side portion of the insulating layer, and in the second process of the lamination step, the cutout portion has an elongated shape having substantially the same length as the external electrode pattern and is formed in each of the two corner portions of the one side portion.
