PROBLEM TO BE SOLVED: To provide a laminated core which prevents the collapse of a lamination of core members and allows connections between ends of core pieces to rotate smoothly. SOLUTION: The laminated core 1 is made by laminating a plurality of belt-like core members 3 formed by connecting the ends of a plurality of plate-like core pieces 2 to each other; a first end 23 of each of core pieces 2 adjacent to one another has a first thin-walled portion 23A whose lower side is removed, and a projection 23B; a second end 24 of each core piece 2 between respective mutually adjacent core pieces 2 has a second thin-walled portion 24A whose upper side is removed, and a protrusion 24B, which lie opposite in location to the projection 23B of a vertically adjacent core piece 2 over the second thin-walled portion 24A, as well as, has a shape in which the projection 23B can be fitted; and thus, the projection 23B is fitted to the protrusion 24B among the core pieces 2 adjacent to each other, to connect individual core pieces 2 making up each core member 3 so that the core pieces 2 are connected freely turnably at their connections.
