ABSTRACT:
A noise filter includes a plurality of resistance patterns arranged in parallel, and a ground pattern opposed to the resistance patterns via a dielectric substrate. Distribution capacitance is caused between the resistance patterns and the ground pattern. The function of the noise filter comes from the distribution capacitance and the resistance of the resistance patterns as the RC composite elements. The noise filters can be connected in plural. Noise can be eliminated without twisting the effective signal components in a compact noise filter.
