PROBLEM TO BE SOLVED: To prevent a resin from invading to a terminal section when a component having a bobbin winding is insert molded. SOLUTION: The method for injection molding comprises the steps of extending a collar 4a of the bobbin 4 on which a coil 3 is wound, providing a connecting terminal 6 at an end of the collar, injecting a resin material to a periphery of an insert member connected to an end of a winding 5 taken out from the bobbin to the connecting terminal, and coating a resin material on the periphery of the coil. The method also comprises a step of molding the resin on a surface of the mold corresponding to the winding disposed on a surface of the collar of the bobbin with molds 20, 21 having a groove 28 of a depth: a diameter of the wire of the winding + 0.02 mm or less.
