A pulse wave monitor includes a sensor unit having a pulse wave sensor and a base. The base of the pulse wave monitor is mounted on a wrist of a subject. A finger or a detector is inserted through the pulse detecting hole provided on the base so as to detect an artery of the subject, and the base is fixed to the wrist of the subject by a belt so that the artery comes to a center of the base. The sensor unit is engaged with the base by a clip. A preliminary position relationship between the sensor unit and the artery is detected. When the position of the sensor unit must be adjusted, the sensor unit is slid to cover a predetermined number of graduations. This adjustment allows the sensor unit to be at an optimal position so that a pulse wave of the subject is measured. As a result, it is possible to provide a pulse wave monitor capable of quickly performing positioning with high accuracy.
