JP-A-2007-301232 discloses a pulse wave measurement device that measures a pressure pulse wave by using a pressure sensor chip in which pressure-sensitive elements are two-dimensionally arranged. For example, JP-A-2007-301232 and JP-A-2004-188183 disclose this kind of press type pulse wave measurement device. In such a press type pulse wave measurement device, it is usual to employ a sensor chip which uses a distortion gauge and a diaphragm, as a pressure-sensitive element.

As a device to which such a press type pressure measurement device is applied, there is a pulse wave measurement device.Ī pulse wave measurement device is a device which, in order to measure a pressure pulse wave that is generated in an artery located in a position which is relatively shallow from the skin of a living body, measures the pressure pulse wave while pressing a substrate having a pressure-sensitive element against the body surface. Usually, a press type pressure measurement device is known which measures a contact pressure against an object to be measured, while applying a pressure against the object to be measured. The present invention relates to a pressure pulse wave sensor and a biological information measurement device. 24, 2015, the contents of which are incorporated herein by reference. 8, 2016 based on Japanese Patent Application (No. This application is a continuation of PCT application No. CROSS-REFERENCE TO RELATED APPLICATION(S)
