An electric compressor includes a rotary shaft, a compression part, a motor including a stator, and a housing. The stator includes a stator core, coils corresponding to a plurality of phases, an insulator, coil ends, first leads of the winding wires, a neutral connection portion, and a cover member. The cover member has a cover end surface opposite from the coil ends. The cover end surface has an accommodation portion in which the neutral connection portion is accommodated. The first leads each include a covered portion, and a non-covered portion. The non-covered portion includes an extension portion continuous with the neutral connection portion extending out from the accommodation portion by a predetermined length. The cover end surface includes a first surface, and a second surface. At least the first surface has a through hole. The first surface is positioned farther from the coil ends than the second surface is.

A stator for a rotating electrical machine includes a stator core, two insulators, and conductive wires forming coils. At least one of the insulators includes guide grooves and through-grooves. The through-grooves include at least two first grooves each of which divides at least two of the guide grooves. Each of the first grooves has a recess that is recessed in the circumferential direction with respect to the rest of the first groove at a portion that divides one of the at least two guide grooves divided by the first groove. The conductive wires extending through the corresponding through-grooves and outward in the radial direction of the insulator base are guided in the circumferential direction by the corresponding guide grooves. The conductive wires extend through the recesses in the corresponding first grooves.
