A pain sensory nerve stimulation apparatus includes: an electrode portion including: a first electrode, a tip end of which is adapted to be inserted into a skin; and at lease one second electrode which is disposed in a circumference of the first electrode without being electrically conductive with the first electrode, and which is adapted to be in contact with a skin; and a stimulation signal supplying unit, supplying a bipolar stimulation signal between the first electrode and the second electrode, the bipolar stimulation signal including a first waveform signal and a second waveform, the first waveform which is convex in a negative direction in the first electrode, the second waveform signal which is convex in a positive direction in the first electrode.

Pain sensory nerve stimulation apparatus

A pain sensory nerve stimulation apparatus includes: an electrode portion including: a first electrode, a tip end of which is adapted to be inserted into a skin; and at lease one second electrode which is disposed in a circumference of the first electrode without being electrically conductive with the first electrode, and which is adapted to be in contact with a skin; and a pulse signal supplier, supplying a pulse signal in which an electrical polarity of the first electrode is set as a anode and an electrical polarity of the second electrode is set as a cathode.

A pain sensory nerve stimulation apparatus includes: a stimulation electrode which is adapted to be attached to a living body, at least one of an exogenous algesic substance and pyrogen which is to be interposed between the living body and the stimulation electrode; and a stimulation power supplier which is configured to supply electric power to the stimulation electrode.
