A pulse wave measuring apparatus includes a sensor unit, a light emitting unit provided on the sensor unit and configured to emit light to a target region that is a body part of a subject, a light receiving unit provided on the sensor unit and configured to receive the light reflected from the target region to generate a received light signal that represents a change in blood flow in the target region, a measuring unit having a principal surface, holding the sensor unit on the principal surface and configured to measure a pulse wave of the subject, from the change in blood flow in the target region, a belt being expandable and configured to wrap around the target region to hold the measuring unit, with the principle surface facing the target region, and an elastic member arranged on the principle surface to surround the sensor unit.
