Coil device and method for manufacturing same and bobbin for coil used therein

Abstract

[Object] To provide a coil device, which is small and can be easily attached to various apparatus without providing a lead wire and can be easily and inexpensively manufactured, and a method for manufacturing the coil device, and a bobbin for coil which is used in the coil device and the method. [Solution] The bobbin for coil 1 according to the present invention is for winding a conductor wire configuring an electromagnetic coil, and contains a first bobbin body 2, a second bobbin body 3 disposed in series to the first bobbin body 2, and a connecting part 4 coupling the first bobbin body 2 and the second bobbin body 3 in series. A connector part 5 incorporating a prescribed number of terminal metal fittings 6 is provided on one axial end portion of the bobbin for coil 1. Thus, since a relatively large space is not required for disposing lead wire(s) as in the prior art, the bobbin for coil is small, so that it can be inexpensively produced.
