A motor includes a stator including a stator core and teeth respectively protruding from the stator core, and coils respectively wound onto the teeth n (n is an integer of 1 or greater) turns including first to n-th turns. The coils are each made from a conductive member having a polygonal cross section. On a cross section obtained when one of the coils is cut in a corresponding one of directions of protrusion of the teeth from the stator core, the one of the coils includes a recess on at least either a first opposing surface representing an opposing surface to a corresponding one of the teeth or a second opposing surface representing an opposing surface to another one of the coils, which is wound onto adjacent one of the teeth. A space allowing refrigerant used for cooling the coils to pass through is provided between the recess and at least either the first opposing surface or the second opposing surface.
