PROBLEM TO BE SOLVED: To provide a high-pass filter which is compact and has excellent characteristics of a high-frequency band. SOLUTION: The high-pass filter includes a pattern wiring provided on a substrate, a capacitor provided on the pattern wiring in series, a GND electrode provided on the substrate in the same plane with the pattern wiring, and an inductor connecting the pattern wiring and GND electrode connected to one of terminals of the capacitor by air cabling using a wire. The wire is so provided that the gap between the GND layer and wire has a value corresponding to a signal pass band that the high-pass filter should have, and a protective film for fixing the wire may be further provided to hold the gap.
