PROBLEM TO BE SOLVED: To provide an electric stimulator with few detection errors, capable of preventing burning of a current detecting circuit or control means caused by the short circuit of loads or short-circuit or malfunction of a transistor used as an outputting stage. SOLUTION: The electric stimulator includes: a stimulation signal generating means for generating a base signal of a stimulation signal; a drive amplifying circuit for generating a driving signal by amplifying the base signal; an output amplifying circuit for outputting the stimulation signal by amplifying the driving signal; a detection circuit for detecting abnormality in loads; a display means for displaying the state of the electric stimulator; a control means for controlling the stimulation signal generating means and the display means based on the detection signal; and a constant current circuit for restraining the electric current of the stimulation signal to prevent false detection caused by noises from outside, etc. The detection circuit detects the voltage variation of the driving signal (approximately 3 V at the maximum).
