PROBLEM TO BE SOLVED: To provide a laminated core and a manufacturing method for the laminated core wherein the iron loss of core pieces and the loss of electromagnetic property are reduced and the efficiency of joint between core pieces is enhanced. SOLUTION: The laminated core 10 is formed as follows: coupling portions composed of at least either of a through groove 25 or a through hole 24 formed in the direction of lamination are formed in laminated core pieces 11; and resin is filled in the formed coupling portions and the laminated core pieces 11 are thereby joined together and integrated. Punched core pieces 11 in a desired shape are subjected to contour cutting and laminated one by one. Thereafter, resin is filled in the coupling portions of the laminated core pieces 11 and the entire core pieces are integrated to form the laminated core 10. COPYRIGHT: (C)2007,JPO&INPIT
