PROBLEM TO BE SOLVED: To provide an electric stimulus applying device and an electric stimulus applying method which are less likely to cause discomfort to a user when applying a weak electric stimulus and heat to a living body or a living body tissue. An electrical stimulus application device is an electrical stimulus application device that applies a weak electrical stimulus to a living body or a biological tissue, and has an electrode portion that outputs the electrical stimulus to the living body or the biological tissue, and the electrical stimulus. The control unit includes a control unit that controls the output, and when the control unit determines that the electrode unit is not in contact with the living body or living tissue, the output of the electrical stimulation is stopped, and the electrode unit is the living body. Alternatively, when it is determined that the electrical stimulation is in contact with the living tissue, the electrical stimulation is output while gradually increasing the output intensity of the electrical stimulation.
