PROBLEM TO BE SOLVED: To provide a device for manufacturing a field coil for a multi-pole DC motor, which prevents a tip of the coil from expanding to the outside during molding and allows the coil to be taken out after molding. SOLUTION: The device for manufacturing a field coil includes a molding device which molds each laminate coil in arc. While a connection pin moves in descending direction of a punch, each coil molding part bends around the connection pin to mold the laminate coil in arc. The device also includes: a movable coil inner periphery guide which guides a coil inner periphery of the laminate coil, a movable coil outer periphery guide which guides the coil outer periphery of the laminate coil, and a coil end part guide for holding the both ends of a continuous coil.
