PROBLEM TO BE SOLVED: To provide a reflection suppression circuit for noise generated in an electric apparatus having a winding. SOLUTION: One end of the reflection suppression circuit A is connected to the winding in the electric apparatus, and the other end is left opened. The reflection suppression circuit A is constituted such that a resistor R is connected to a distribution constant circuit composed of a coil L that has a resonance frequency characteristic same as resonance generated by a distribution constant or a concentration constant in the apparatus. By this, resonance is generated at the winding in the electric apparatus, resonance is also generated in the reflection suppression circuit A, and potential differences are generated at both ends of the reflection suppression circuit A. By the potential differences, the reflection of noise into the electric apparatus can be suppressed by making a current flow into the resistor of the reflection suppression circuit A and heating the resistor.
