Abstract
Abstract A small-sized low frequency curing apparatus which can be applied directly to the object to be stimulated such as a body or the like. Generating high frequency boosted pulses by electrical energy from a small-sized power source, accumulating the boosted pulses temporarily until a predetermined amount at which stimulation is effective for the organism is reached, and then discharging the accumulated charges to generate low frequency pulses having an effective amplitude for the stimulation as an electrical stimulation. Thus, it is possible to apply a sufficient magnitude of and a stable electrical stimulation to an object to be stimulated regardless of the small capacity of the small-sized power source.
