PROBLEM TO BE SOLVED: To provide a pulse wave detector capable of improving the accuracy of detecting a pressure pulse wave.SOLUTION: A biological information measuring device comprises: a pressure wave detection unit 10 detecting a pressure wave from a radial artery by a pressing surface 10a with a pressure detection element formed thereon being pressed against the radial artery under a skin of a wrist of a subject and an enclosure 20 containing the pressure pulse detection unit with the pressing surface exposed to the wrist side. The enclosure is configured such that a compression pressure caused by the enclosure when the enclosure is worn around a wrist is smaller than a compression pressure caused by the pressing surface when the enclosure is worn.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】圧脈波の検出精度を向上させることのできる脈波検出装置を提供する。【解決手段】生体情報測定装置は、圧力検出素子が形成された押圧面10aを被測定者の手首の皮膚下の橈骨動脈に押し当てて、橈骨動脈から圧脈波を検出する圧脈波検出部10と、押圧面を手首側に露出させた状態で圧脈波検出部を収容する筐体20と、を備える。筐体は、手首に装着した装着状態における筐体による橈骨動脈への圧迫圧力が、装着状態における押圧面による橈骨動脈への圧迫圧力よりも小さくなるように構成されている。【選択図】図2
