Abstract
To provide a pain evaluation device, a pain evaluation method, and a non-transitory storage medium storing a pain evaluation program that can evaluate the degree of pain in each individual. A control unit includes: an electrocardiographic waveform acquisition unit configured to acquire electrocardiographic waveform data of a user; and a pain determination unit configured to determine, based on a comparison between first electrocardiographic waveform data obtained by the electrocardiographic waveform acquisition unit in a state where no physical load is applied to the body of the user and second electrocardiographic waveform data obtained by the electrocardiographic waveform acquisition unit in a state where a load is applied to the body of the user, a degree of pain sensed by the user in a state where the load is applied.
