Abstract:
[Problem] The purpose of the present invention is to provide a coil device that is small in size, can be easily attached to various devices, and can be easily and inexpensively manufactured without providing a lead wire, a method of manufacturing the same, and a coil bobbin used therein. [Solution] The coil device 1 of the present invention, which is for winding a conductive wire constituting an electromagnetic coil, comprises: a first bobbin body 2; a second bobbin body 3 that is disposed in series to the first bobbin body 2, and a connection part 4 that connects the first bobbin body 2 and the second bobbin body 3 in series to each other, and a connector part 5 in which a predetermined number of terminal fittings 6 are embedded is disposed at one end portion of the coil bobbin 1 in an axial direction. Therefore, since a relatively large space for providing the lead wire as in the related art is not required, the coil device is thus small, and as a result, can be manufactured at low cost.
