PROBLEM TO BE SOLVED: To facilitate matching the delays of both signal lines with each other, and also cancel out undesired signals. SOLUTION: The voltage-controlled oscillating circuit includes an oscillation circuit unit 1, an output branching circuit 2 for branching an oscillation signal and for separate output of first and second signals whose phases are mutually inverted, trap circuits 3 and 4 connected in parallel to an output stage of the output branching circuit 2 and having the same configuration with trap frequencies different, and an output recombining circuit for combining outputs of the trap circuits. A voltage control signal of the oscillation circuit unit 1 is applied to varactor diodes 32 and 34 of the trap circuits 3 and 4 to interlock a trap frequency of the trap circuits 3 and 4 with an oscillation frequency.
