PROBLEM TO BE SOLVED: To provide a small laminated filter module that has a small amount of electrical coupling among a plurality of built-in filters. SOLUTION: The axes of the inductors L1 to L3 of resonators Q1 to Q3 constituting a bandpass filter BPF1 cross orthogonally with those of the inductors L4 to L6 of resonators Q4 to Q6 constituting a bandpass filter BPF2. The inductors L1 to L3 are respectively constituted of patterns of the inductors 61a, 61b, 62a, 62b, 63a and 63b formed on the surfaces of insulation sheets 46 and 48. The inductors L3 to L6 are constituted of patterns for the inductors 64a, 64b, 65a, 65b, 66a and 66b formed on the surfaces of the insulation sheets 46 and 48.
