An electric compressor includes a housing, a rotary shaft rotatably supported in the housing, a motor that rotates the rotary shaft, and a compression part that compresses fluid. The housing includes a boss protruding toward the motor, and the boss has an inner peripheral surface in which a bearing that supports the rotary shaft is provided. The boss has an asymmetrical shape and has an outer peripheral surface that varies in distance from the inner peripheral surface in a radial direction of the rotary shaft. The rotary shaft is press-fitted in the bearing, and the bearing is fitted in the inner peripheral surface with a clearance between the bearing and the inner peripheral surface.
