Abstract
A skin-contact type medical treatment apparatus is provided which includes: a first conductive member having a first skin-contact surface in contact with a first surface of skin when in use, the first skin-contact surface being made of metal or its alloy; and a second conductive member having a second skin-contact surface in contact with a second surface of skin different from the first surface when in use together with the first conductive member, the second skin-contact surface being made of n-type semiconductor material having a standard single electrode potential lower than that of the first skin-contact surface. The first and second conductive members are electrically connected by a protective resistor at an area different from the first and second skin-contact surfaces, the protective resistor having a resistance value in the range of from 0.1 to 50 M.OMEGA..
