Abstract
A grip-type pulse wave measuring device includes a main body that has a substantially spheroid shape, and a stopper that projects along an axial direction of the main body and abuts against a side surface of a thumb to restrict a position of the thumb when a user grips the main body portion. Moreover, a light shielding cover is provided that is formed into a substantially semi-cylindrical shape and is mounted so as to be swingable about, as a swing shaft, a shaft that is provided in parallel to the axial direction of the main body. A photoplethysmographic sensor is disposed at a position offset from the swing shaft of the light shielding cover along a peripheral direction of the main body and is configured to acquire a photoplethysmographic signal.
