Claim:
1. An electric stimulator, comprising: a housing, which comprises an internal space formed therein and an outside surface in which at least one electrode plate retention slot is formed; a control circuit board, which is mounted in the internal space of the housing to control intensity and frequency of a current output; at least two electrode plates, which are electrically conductive and are received and retained in the electrode plate retention slot of the housing and are in electric connection with the control circuit board, the electrode plates having an outside surface that comprises a large-area contact surface and a small-area contact surface connected to the large-area contact surface, the large-area contact surface having a surface area that is greater than a surface area of the small-area contact surface, the large-area contact surface and the small-area contact surface defining therebetween an included angle that is not equal to 180 degrees; wherein the electrode plates each comprises a first flat section and a second flat section that are connected to each other at a predetermined angle therebetween and wherein the first flat section comprises the large-area contact surface and the second flat section comprises the small-area contact surface, the predetermined angle between the first and second flat section being the included angle defined between the large-area contact surface and the small-area contact surface.
