To provide a polar-type bandpass filter that can generate n/2 pieces of attenuation poles, when a circuit order is set to (n).

This polar type bandpass filter has a first coupling loop element connected to one I/O terminal, a second one connected to the other, and a plurality of resonance elements arranged between the first and second coupling loop elements. In this case, in the portion between the first and second coupling loop elements, a subcoupling circuit is provided. The subcoupling circuit has a capacity coupling circuit, a coupling line, and a magnetic coupling circuit, and generates the attenuation pole in the attenuation region of the polar type bandpass filter.
