PROBLEM TO BE SOLVED: To keep the subject-contacting portions hygienic by making the portions easily replaceable and minimize the portions to be replaced.SOLUTION: A biological information measuring probe (1A-1G) includes: a cable 14 which has ends respectively connecting to a light emitting element 12 and a light receiving element 13 and another end connecting to a measurement device main body 10 for transfer of signals a transparent member 15 which is transparent to illumination light from the light emitting element, and which covers a portion 2 of the living body to prevent the portion of the living body from directly contacting the light emitting element, the light receiving element, and the cable when the probe is mounted to the portion of the living body and a transparent member 16 which is transparent to light to be received by the light receiving element. The probe is further provided with an exterior body (11A-11G) which serves as a contacting part to the portion of the living body. The exterior body is configured to be detachably attached to the cable, and the light emitting element and/or the light receiving element.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】被験者に接触する部分を交換容易にすることで衛生性を保ちつつ、交換部を極力少なくする。【解決手段】生体情報測定用プローブ(1A-1G)は、一方で発光素12子及び受光素子13に接続し、他方で測定装置本体10に接続し信号を伝送するケーブル14と、生体部位(2)に装着されるときに発光素子及び受光素子並びにケーブルが直接生体部位に接触しないようにこれらを被覆するとともに、発光素子からの投光用の光を透過する透過部材15と、受光素子への受光用の光を透過する透過部材16とを有し、生体部位に装着されるときに当該生体部位への接触部となる外装体(11A-11G)とを備える。外装体は、ケーブルと、発光素子又は/及び受光素子に対して着脱可能にされている。【選択図】図1
