PROBLEM TO BE SOLVED: To operate as a low-pass filter to a common-mode current so as to form a signal blocking band to a frequency of several hundred MHz or more and provide a transmission characteristic of low loss to a differential-mode current. SOLUTION: A pair of grounding conductor layers 6 and 11 are formed respectively on the front and rear surfaces of a laminated dielectric substrate, and a pair of linear conductors 21 and 22 are provided in parallel between the grounding conductor layers 6 and 11 in the dielectric substrate. The conductors 21 and 22 electrically connect conductor sections 7a and 8a whose patterns are formed close to and parallel to the grounding conductor layer 6, with conductor sections 9a and 10a whose patterns are formed close to and parallel to the grounding conductor layer 11 respectively.
