Abstract

Provided is a print circuit board including: a ground conductor layer; a pair of strip conductors extending along a first orientation; a first resonator conductor three-dimensionally intersecting with the pair of strip conductors along a second orientation; a pair of first via holes connecting the first resonator conductor and the ground conductor layer; and a dielectric layer including the first resonator conductor therein, and being disposed between the ground conductor layer and the pair of the strip conductors. A distance Hi between the pair of strip conductors and the ground conductor layer is twice or more a distance Hbetween the pair of strip conductors and the first resonator conductor, and a line length L of the first resonator conductor is 0.4 wavelength or more and 0.6 wavelength or less at a frequency corresponding to the bit rate.
