PROBLEM TO BE SOLVED: To provide a laminate core inexpensively which constitutes a closed magnetic circuit shaped likeθhaving superior electric characteristics and not requiring a weld process. SOLUTION: This laminate core constitutes a closed magnetic circuit shaped likeθ, in which an E block E1 having silicon steel plates layered to provide taper joint faces a1, a2 at the outside of external magnetic pole parts at both sides and a male V-shaped taper joint face (c) at a central magnetic pole part is butted to an E block E2 having silicon steel plates layered to provide taper joint faces a1, a2 at the inside of the external magnetic pole parts at both sides and a female V-shaped taper joint face (c) at the central magnetic part.
