A low-frequency electric therapy apparatus is provided with: a pair of pads 300 and 300 each of which can change the position and the area of an energizing area； and a wave form generation and output portion 250 which applies a treating current between an energizing area of one pad 300 and that of the other pad 300. While the wave form generation and output portion 250 outputs the treating current, the output portion 250 produces a kneading stimulus or a rubbing stimulus by changing the position and/or the area of the energizing area of at least one pad. Thereby, there is provided a low frequency electric therapy apparatus having a simple configuration which may produce more similar bodily sensation to that of "kneading", and "rubbing" performed by a person, and has excellent convenience.一種低頻治療器，具有：一對墊片300、300，各自能變更通電區域之位置及面積；及波形生成/輸出部250，流通治療電流在一方墊片300之通電區域和另一方墊片300之通電區域之間。波形生成/輸出部250，係藉由一邊輸出治療電流一邊至少變化1個墊片300之通電區域位置及/或面積，而作出搓揉刺激或摩擦刺激。藉此，提供一種雖係簡易構成但可作出更近乎由人所施行的「搓揉」或「摩擦」之體感，而且使用便利性優越之低頻治療器。
