PROBLEM TO BE SOLVED: To provide a low-frequency therapeutic device that can be downsized.SOLUTION: A low-frequency therapeutic device 1 includes: a pad 2 provided with a through-hole 2H in which pad side electrodes 2E and 2F are formed on a reverse face 2T； a holder 3 disposed at a reverse face 2T side of the pad 2 so as to face the pad side electrodes 2E and 2F； a body 4 having body side electrodes, which is detachably attached to the holder 3； and wiring members 5A and 5B for electrically connecting the body side electrodes and the pad side electrodes. The wiring members include a first end part connected to the body side electrodes, a second end part connected to the pad side electrodes, and conduction parts 5A3 and 5B3 that conduct the first end part and the second end part, a part of which is arranged so as to pass through the through-hole 2H.SELECTED DRAWING: Figure 3【課題】小型化することが可能な低周波治療器を得る。【解決手段】低周波治療器１は、貫通孔２Ｈが設けられるとともに、裏面２Ｔにパッド側電極２Ｅ，２Ｆが形成されたパッド２と、パッド側電極２Ｅ，２Ｆに対向するようにパッド２の裏面２Ｔの側に配置されたホルダ３と、本体側電極を有し、ホルダ３に着脱可能に取り付けられる本体４と、本体側電極とパッド側電極とを電気的に接続する配線部材５Ａ，５Ｂとを備える。配線部材は、本体側電極に接続される第１端部と、パッド側電極に接続される第２端部と、第１端部と第２端部とを導通させ、自身の一部が貫通孔２Ｈを通り抜けるように配置される導通部５Ａ３，５Ｂ３とを含む。【選択図】図３
