Transmission line type noise filter with small size and simple structure, having excellent noise removing characteristic over wide band including high frequency band |
摘要 |
A transmission line type noise filter includes a metal fine wire (1) made of valve-operational metal and serving as a central conductor, a capacitance forming portion (3) formed over a predetermined length on the periphery of the metal fine wire, and a conductor layer (2) formed on the surface of the capacitance forming portion and serving as an external conductor. The capacitance forming portion (3) includes a sintered body (11) formed on the metal fine wire and made of the foregoing valve-operational metal, a dielectric film (31) formed on the surface of the sintered body and serving as a dielectric, and a solid electrolyte layer (23) formed on the surface of the dielectric film.
