Abstract

Provided is a technique for reducing a possibility of uneven flow rates of a refrigerant. A stator core (100) is an annular stator core and includes: a first core (10) including first circumferential refrigerant paths (11) that are formed in a circumferential direction at a plurality of positions at a distance from one another and serve as flow paths for a refrigerant extending in the circumferential direction; a second core (20) including second circumferential refrigerant paths (21) that are formed in the circumferential direction at a plurality of positions at a distance from one another and serve as flow paths for the refrigerant extending in the circumferential direction; and a third core (30) in which a plurality of axial refrigerant paths (31) serving as flow paths for the refrigerant that extend in the axial direction and open at ends in the axial direction are formed. The first core (10) and the second core (20) are adjacent in the axial direction, each of two ends in the circumferential direction of the first circumferential refrigerant path (11) is connected to a different one of the two second circumferential refrigerant paths (21), and a plurality of the axial refrigerant paths (31) are connected to at least one of the first circumferential refrigerant paths (11) or one of the second circumferential refrigerant paths (21).
