Abstract
A pressure pulse wave transmitting sheet for being interposed between a skin surface of a living subject such as a patient and a pressure pulse wave sensor set on the skin surface in pressed contact therewith, the sensor having a press surface in which at least one pressure sensing element is provided and which is pressed against the skin surface so that the at least one pressure sensing element detects a pressure pulse wave transmitted from an artery of the subject underlying the skin surface, to the press surface via the sheet, the sheet being formed of an elastic material having a hardness substantially equal to a hardness of human being's skin.
