<P>PROBLEM TO BE SOLVED: To provide a surge absorbing circuit which is reduced in size over the entire circuit, suppresses a higher harmonic leak current by keeping a high impedance characteristic over the whole frequency region, operates at a voltage smaller than an insulation test voltage when a lightning surge is applied and does not operate during an insulation test. Ž<P>SOLUTION: The surge absorbing circuit is equipped with a first surge absorber 1 and a second surge absorber 2 which are connected in series; a first resistor 5 connected in parallel to the first surge absorber 1; a second resistor 6 connected in parallel to the second surge absorber 2; and a capacitor 7 connected in parallel to the second resistor 6.
