PURPOSE:To obtain a resonator with a low resonance frequency without increasing the size of base by crossing at least part of a coil pattern on front and rear sides of the dielectric base so as to cause mutual induction coupling. CONSTITUTION:Capacitor patterns 2, 3 are opposed at both faces of the dielectric base 1, the coil patterns 4, 5 are formed in a meandering shape, one end is connected to capacitor electrode patterns 2, 3 and the other end is connected while being bypassed with the base end face. Part of the two coil patterns is crossed via the base 1 and in flowing a current, the magnetic field caused in each coil pattern by said current is directed additively. Thus, the resonance frequency is decreased without changing the size of base and miniaturization and low cost are realized in comparison with a conventional resonator having the same resonance frequency.
