The purpose of the present invention is to provide an inductance device capable of improving withstand voltage between a front end of a terminal part and a magnetic core. In the inductance device in which a coil is embedded inside the magnetic core, the end parts of a pair of belt bodies extended from the coil are bent so that a pair of terminal parts (15, 18) are formed on the outer surface of the magnetic core. The surface of the conductive belt body (11) is coated with a coating resin layer (12) (a first insulating layer) besides a front end surface (24) of the terminal part. A gap (25) is installed between the front end surface (24) of the terminal part and a sidewall (20b) of a magnetic core (20) facing the front end surface. The gap (25) is filled with a protective resin layer (41) (a second insulating layer). |
