Abstract
A high-frequency circuit board capable of easily forming a bias line whose resonance frequency is sufficiently separated from operating frequency is provided. On a high-frequency circuit board, by electrically connecting a bias lineto a high-frequency circuitusing blind via holesand, it is possible to limit the route that has a possibility of producing resonance only to the bias line connecting the endsandof the blind via holesandto the bias line. By adjusting the route length from the endto the end, it is possible to prevent production of resonance in the vicinity of the operating frequency.
