Abstract: A noise filter and terminal structure therefor are disclosed. An insulator case composed of a case main body and a cap are utilized, with the case main body including coil fixing projections and capacitor position restricting ribs. A plurality of metallic terminals provide electrical connections to the electrical components within the insulator case and extend out of that case between adjacent edges of the case main body and cap. The metallic terminals are generally flat, with a generally U-shaped bent portion and a connection part extending from the bent portion. The bent portion is fitted into a corresponding concave part in the case main body. The connection part includes hook-shaped projections adapted to hold a wire, and the projections of all terminals are at generally the same level to facilitate automatic soldering.
