PROBLEM TO BE SOLVED: To provide a pulse wave detection device whose mountability can be improved, while suppressing a positional deviation of a pulse wave detection sensor.SOLUTION: A pulse wave detection device used by being mounted on a wrist H of a person to be measured includes a housing 20 that accommodates a pulse wave detection part 10 for detecting a pulse wave from a radial artery TD. The housing 20 includes a first housing part (1a, 1b) and a second housing part (2) whose rigidity is lower than the rigidity of the first housing part. The pulse wave detection part 10 is accommodated in the first housing part (1a), and in a state that the housing 20 is mounted on the wrist, a region 2c of the housing 20 that comes in contact with a styloid process Ta of the radius T of the wrist H is composed at least of the second housing part (2).SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】脈波検出センサの位置ずれを抑制しつつ、装着性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】被測定者の手首Hに装着して用いられる脈波検出装置であって、橈骨動脈TDから脈波を検出する脈波検出部10を収容する筐体20を備え、筐体20は、第一の筐体部(1a,1b)と、第一の筐体部よりも剛性の低い第二の筐体部(2)と、を含み、第一の筐体部(1a)に脈波検出部10が収容されており、筐体20が手首に装着された状態で、手首Hの橈骨Tの茎状突起Taと接触する筐体20の領域2cが、少なくとも第二の筐体部(2)で構成されている。【選択図】図2
