Abstract
A method of manufacturing a laminated stator core includes: blanking an electrical steel sheet at 1st to Nth (N is a natural number equal to or greater than 2) positions arranged in the width direction of the electrical steel sheet to form 1st to Nth blank members, and laminating the 1st to Nth blank members to form a laminated stator core. The shape or arrangement of at least one odd-shaped part of a plurality of odd-shaped parts in the kth (k is a natural number of 1 to N) blank member differs from the shape or arrangement of at least one odd-shaped part of a plurality of odd-shaped parts in the mth (m is a natural number of 1 to N and satisfying m≠k) blank member such that the shapes of given two blank members do not agree with each other.
