ABSTRACT:
A skin-contact type medical apparatus is formed of a first element for forming a pedestal, a protective resistance element attached to the first element, and a second element formed of an n-type semiconductor element and attached on one end of the protective resistance element away from the first element. The first element has a skin-contacting surface and a concave portion opened at a side of the skin-contacting surface to receive the protective resistance element. The protective resistance element has an elongated shape and a voltage controlling function. When the apparatus contacts the skin, the first and second elements serve as positive and negative electrodes, respectively, and the second element is electrically connected to the first element through the protective resistance element.
