PROBLEM TO BE SOLVED: To provide a brushless motor wherein the connections of stator coils in multiple phases and connection terminal units can be reliably molded by a simple technique without incurring additional cost. SOLUTION: The brushless motor is formed by integrating the connections 90 of the connection terminal frames 62 of the connection terminal units 60 and the terminal portions 72 of the stator coils 70 with a resin member by molding using a metal mold. The connection terminal units 60 are provided in proximity to the connections 90 with wall-like molten resin inflow suppressing portions 68 that suppress the flow of molten resin during molding. Thus, even if high-pressure molten resin flows from the gate of the metal mold into the cavity during molding, the flow of this molten resin can be suppressed by the molten resin inflow suppressing portions 68. Therefore, the connections 90 can be prevented from being cut, the connection terminals 64 can be prevented from being bent, and the connections 90 can be molded with reliability.
