PROBLEM TO BE SOLVED: To provide a pulse wave sensor for highly accurately measuring pulse waves without restricting the behavior of a subject.SOLUTION: The pulse wave sensor 1 includes: a casing 10 to be attached to an external ear E and an optical sensor section 11 which is provided in the casing 10, and acquires pulse wave data by irradiating the external ear E with light emitted from a light-emitting section 11A and detecting by a light-receiving section 11B the strength of the light returning after passing through the living body.COPYRIGHT: (C)2013,JPO&INPIT【課題】被験者の行動を制約せず高精度に脈波測定を行う。【解決手段】脈波センサ1は、外耳Eに装着される筐体10と、筐体10に設けられて発光部11Aから外耳Eに光を照射し生体内を透過して戻ってくる光の強度を受光部11Bで検出することにより脈波データを取得する光センサ部11と、を有する。【選択図】図3
