摘要： PROBLEM TO BE SOLVED: To provide a laminated filter circuit from which a greater attenuation gradient can be obtained.
SOLUTION: The laminated filter circuit 1A includes a resonance inductance 2A, DC block capacitors 6A, 6C, resonance capacitors 6B, 6D, and a trap capacitor 6F.

The trap capacitor 6F is obtained by connecting an input terminal 7 and an output terminal 8 in series with each other. Since an attenuation pole is formed at each of frequencies in a low frequency side attenuation band and a high frequency side attenuation band and around a pass band in this way, the attenuation gradient is increased.
