PROBLEM TO BE SOLVED: To provide a high-frequency circuit which is provided with a termination resistor buried in a board surface, and which is capable of suppressing the reflection of an inputted high-frequency signal.SOLUTION: A high-frequency circuit 10 includes: a termination resistor 12a buried in the surface of a circuit board 21; and a signal line 11a which is a signal line formed on the surface of the circuit board 21, and, assuming a section of the signal line defined by the front of its termination point as a start position and the termination point as an end position to be a junction section CJ of the signal line, the junction section CJ hanging over a position of the top face of the termination resistor 12a, and a length of the signal line 11a from the start position to the end position being connected to the termination resistor 12a in at least a portion in width direction of the junction section CJ. The width Wof the signal line 11a at the start position of the junction section CJ is greater than or equal to the width Wof the top face of the termination resistor 12a at the start position. |
