PROBLEM TO BE SOLVED: To provide a means capable of measuring easily, accurately and stably a characteristic of an electronic component. SOLUTION: This filter module 1 for evaluating the characteristic has a wiring board 2 mounted with a SAW filter 3 of an evaluation object and coupled integrally with input side and output side connectors 4, 5. A wiring pattern of the wiring board comprises linear input side and output side wires 11, 13 comprising wiring portions 11a, 11b, 13a, 13b divided by slots 12, 14, and grounding side wires 15, 16, 21, 22 arranged separately with a slight distance in sideways thereof. A desired impedance matching circuit is constituted by selecting a section between the fellow input side and output side wiring portions, and a section between the grounding side wires adjacent thereto to be connected directly with a coil or a capacitor.
