ELECTRIC COMPRESSOR

Provided is an electric compressor in which there are fewer instances of a magnetic force line being blocked more than necessary by a through-hole for a bolt, the number of components and number of machining steps do not increase as much, and the degree of adhesion of a laminated steel plate can be increased to ensure stiffness. A stator has a stator core () configured by laminating a plurality of electromagnetic steel plates in an axial direction, the electromagnetic steel plates having a substantial ring shape as seen from the axial direction. As seen from the axial direction, a plurality of through-holes () are formed through the stator core () in the lamination direction of the electromagnetic steel plates, on the same circle centered around the axis line, and as seen from the axial direction, a first arc length (L) or a second arc length (L) longer than the first arc length (L) is set as each arc length between through-holes () adjacent in the circumferential direction. The stator is secured to a housing by a bolt inserted through the through-holes (), the stator core () is varnished at least in areas near the centers in the circumferential direction between through-holes () where the second arc length (L) is set.
