Abstract
A biological-information measuring device functioning as a pulse-wave measuring module includes a light emitter configured to emit light to a test object and a light receiver configured to receive reflected light from the test object. The light receiver includes a light detector (a light receiving element) configured to detect the reflected light and an optical filter disposed on the light detector (the light receiving element) and configured by a plurality of layers. A layer most distant from the light detector (the light receiving element) among the plurality of layers of the optical filter is formed by a silicon oxide layer made of silicon oxide.
