Abstract
A pulse wave measurement device of the present invention includes a transmitter configured to emit a radio wave toward a measurement target site, a receiver configured to receive the radio wave reflected from the measurement target site, and a pulse wave detector configured to detect, based on an output of the receiver, a pulse wave signal representing a pulse wave of an artery passing through the measurement target site. The radio wave emitted from the transmitter has a bandwidth narrowed by a predetermined bandwidth index.

A pulse wave measurement device configured to measure a pulse wave of a measurement target site of a living body, the pulse wave measurement device including:
- a transmitter configured to emit a radio wave toward the measurement target site;
- a receiver configured to receive the radio wave reflected from the measurement target site;
- and
- a pulse wave detector configured to detect, based on an output of the receiver, a pulse wave signal representing a pulse wave of an artery passing through the measurement target site and/or a tissue adjacent to the artery, wherein
- the radio wave emitted from the transmitter has a bandwidth narrowed by a predetermined bandwidth index.
