PROBLEM TO BE SOLVED: To provide a large power noise filter with a high current capacity and a high withstanding voltage for effectively attenuating electric noises with high frequencies. SOLUTION: The electric noise filter is configured by arranging a circuit element with an impedance different from a characteristic impedance of a transmission line between a main conductor of a sub conductor missing part and a sub conductor or between the main conductor of the sub conductor missing part of the transmission line and a third conductor or by annularly providing a magnetic body to the transmission line, the transmission line being configured with the main conductor and the sub conductor coaxially coated on the main conductor via an insulator, the sub conductor being divided into a plurality of conductors at a prescribed uniform interval or by two kinds or more of lengths, the adjacent sub conductors being interconnected by the third conductor, or part of the removed sub conductors through the division being left and used for the interconnection in place of the third conductor.
