PURPOSE: To provide the resonance circuit unit which can be manufactured at a low cost.
CONSTITUTION: Concerning the resonance circuit unit provided with an inductance element (1) and a capacitance element (2) and equipped with a resonance frequency decided by both of these elements, the inductance element (1) is formed by cutting a planar conductor, and the capacitance element (2) is provided with a first electrode (2a) formed by cutting the planar conductor and a second electrode (2b) formed by cutting and raising the planar conductor and bending it so as to face the first electrode with a dielectric inbetween. Concerning the manufacture of this resonance circuit unit, the inductance element (1) is formed integrally with the capacitance element (2) by cutting the planar conductor in the shape of a coil so as to arranged the first electrode (2a) of the capacitance element (2) at the central part and to arrange the second electrode (2b) of the capacitance element (2) on the outside, and the second electrode (2b) is folded so as to face the first electrode (2a) with the dielectric inbetween.
