Air compressor for a vehicle having improved internal cooling efficiency by ensuring a circulation flow of compressed air for internal cooling and allowing the compressed air to sufficiently flow. The air compressor comprises: a housing with a compression unit for introducing and compressing air from outside; a motor unit which includes a rotor and a stator, and drives the compression unit to rotate according to the rotation of the rotor; a bearing unit supporting the rotor to be rotatable; a cooling circulation flow path formed inside the housing for moving, in an axial direction, some of the air compressed in the compression unit and circulating the air to the compression unit; and a bypass flow path which receives some of the air passing through the cooling circulation flow path and bypasses a partial region of the bearing unit to join the cooling circulation flow path.
