Abstract
A pulse wave sensor includes a detecting element and a sensor body. The pulse wave sensor is worn on the back side of a user's wrist corresponding to the back of the user's hand. The detecting element includes a translucent member on its top, and the translucent member has a convex surface. The detecting element is attached on the back side of the user's wrist by a dedicated belt so that the convex surface of the translucent member is in intimate contact with the surface of the user's skin. The sensor body is attached on the back side of the user's wrist by another dedicated belt so that it is arranged on the detecting element. A cushion is arranged between the sensor body and the detecting element. The pulse wave sensor can stably detect the pulse wave without being affected by the movement of the user's wrist.
