Pain measurement device

The present invention uses a measured degree of pain for disease diagnosis or for comparison with the degree of pain experienced by another measurement subject. A pain measurement device 1 is providedwith electrodes 3a that are attached to a measurement subject 2, and an electrical stimulation current generating means that generates an electrical stimulation current to be supplied to the electrodes 3a. Pain felt by the measurement subject 2 is measured on the basis of the electrical stimulation current applied to the measurement subject 2 from the electrodes 3a. The pain measurement device isprovided with a means for displaying the relationship between a value selected by the measurement subject 2 on a VAS or faces pain scale and a pain measurement value that is a logarithmic value or alogarithm-like numerical value of a value that is based on the electrical stimulation current. 本发明提供的疼痛测定装置，能够利用所测得的疼痛程度与其他测定对象的疼痛程度进行比较或者诊断病名；疼痛测定装置(1)具备安装于测定对象(2)的电极(3a)和生成供给至电极(3a)的刺激电流的刺激电流生成单元，并根据从电极(3a)施加于测定对象(2)的刺激电流来测定测
