Claims

[Scope of utility model registration request]

A plurality of hot line side electrodes 5 are formed on one main surface of the dielectric substrate main body 4, and a series of ground side electrodes 6 opposite to the electrodes 5 are formed on the other main surface, Hotline side electrode 5... chip coil 7 between
are connected to form a filter circuit board 1, and this filter circuit board 1 is inserted into and attached to a holding frame 2 made of an electrically insulating material in a constant posture via a guide part 8, and a plurality of leads implanted in the holding frame 2 are connected. The LC7 filter is constructed by connecting connecting pieces 9a and 10a formed at the inner ends of the terminals 9 and 10 to the hot line side electrodes 5 and 5 and the earth side electrode 6, respectively, and covering the holding frame 2 with the protective member 3.
