Abstract
A laminated core manufacturing method according to the present invention is a manufacturing method for a laminated core including: a laminated body that is configured by laminating core strips that are made of a magnetic material, the laminated body including: a core back portion; and a tooth portion; and electrically insulating members that are disposed on two side portions of the tooth portion, wherein the laminated core manufacturing method includes a bonding step in which the insulating members are pressed onto each of the side surfaces of the tooth portion of the laminated body so as to integrate the laminated body and also so as to fix the insulating members to the laminated body, by means of at least one of an adhesive and a pressure-sensitive adhesive that is disposed between each of the side surfaces of the tooth portion and the insulating members.
