Abstract
Provided is a stator core of a rotating electrical machine in which a core back and teeth are formed by laminating a plurality of thin steel plates with an adhesive interposed therebetween. The stator core includes a first stator core that is formed by applying the adhesive to a first region covering the core back and the teeth between the plurality of thin steel plates, and a second stator core that is formed by applying the adhesive to a second region, which has an area smaller than an area of the first region, between the plurality of thin steel plates. The first stator core is disposed at least at one end of the stator core in a laminating direction of the thin steel plates.
