ABSTRACT:
To provide an electric compressor in which the occurrence of shrink-fitting failures can be prevented when a stator is shrink-fitted in a motor case. Provided are a casing (67) in which the inner circumferential surface of the cylinder is provided with a first inner circumference (101) and a second inner circumference (103) whose radius is larger than the first inner circumference (101), the inner circumference (101) having an inclination that becomes more distant from a central axis (C) from a bottom face (79) toward an opening (85); a compressing unit that compresses fluid; and a rotor and a stator that rotationally drive the compressing unit, wherein the first inner circumference (101) and the second inner circumference (103) are provided with a substantially cylindrical insertion surface (105) whose radius is larger than the second inner circumference (103) and in which the stator is inserted; and at least the first inner circumference (101) is provided with an enlarged diameter portion (109) whose radius is larger than the insertion surface (105) and which makes the distance from the end at the opening (85) side of the insertion surface (105) to the opening (85) substantially equal.
