To provide small high-frequency circuit components having small variations, in a stray capacitance generated between an inductor pattern and a capacitor electrode pattern, accordingly having small variations in the characteristics.

The inductor pattern 19 is overlaid with the capacitor electrode pattern 21 in a plan view; that means the projection of the pattern 19 onto the pattern 21 is included within the pattern 21 in a laminating direction. Specifically, outer dimensions of W1, L1, D1 of the pattern 19 and corresponding outer dimensions W2, L2, D2 of the pattern 21 satisfy the following conditional equations: W2=W1+(0.1 mm to 1.0 mm), L2=L1+(0.1 mm to 1.0 mm) and D2=D1+(0.1 mm to 1.0 mm).
