1. A thrust magnetic bearing, comprising:
a coil formed by winding a conductive wire;
a core that houses the coil, the core being provided with a refrigerant inlet and a refrigerant outlet;
a refrigerant flow path connecting the refrigerant inlet and the refrigerant outlet, the refrigerant flow path being provided between the coil and the core, and the refrigerant flow path including a main flow path extending along the coil in the winding direction of the coil; and
an insulating member that insulates the coil and the core from each other,
the refrigerant flow path being formed so that a refrigerant flowing from the refrigerant inlet to the refrigerant outlet mainly flows along the coil in a winding direction of the coil,
the insulating member being disposed on both sides in an axial direction of the coil and on a radially inner side of the coil, and
the main flow path including a gap between a radially outer side of the coil and the core.
