Abstract: A wave providing accessory using a sawtooth waveform is disclosed. The wave providing accessory using a sawtooth waveform comprises: a stimulus generator for generating a micro current having a wavelength of a sawtooth wave; a first decoration member which is provided in the form of a metal plate or housing, has one surface to which the stimulus generator is fixed, is electrically connected to the stimulus generator so that the micro current generated by the stimulus generator is applied thereto, and has a decorative pattern engraved on one surface of the plate or an outer surface of the housing; and a wearable member which is provided in the form of a metal ring that is wearable on one of a wrist, a neck, and an ankle, is connected to the decoration member to allow the micro current applied to the decoration member to be also applied thereto, and transfers the applied micro current to a human body along with the decoration member.
