The article related to the design of this application is a "biological information measuring device" that is used with a sensor attached to the user's forehead. The sensor includes electrodes and collects data related to biological information such as brain waves, myoelectric potential, sweating amount, body temperature, body water content, pulse wave, sound, and acceleration of a part. The exterior of the "forehead contact part" shown in the reference drawing representing the names of each part is a soft material having elasticity such as silicon rubber.
