PROBLEM TO BE SOLVED: To provide a band for wearing sensors capable of reducing the number of components and giving no trouble to a user when wearing the sensor at a predetermined tension, and a bioinformation apparatus.SOLUTION: This band for wearing sensors has elasticity, is wound around in such a mode as clamping a sensor 30 for detecting bioinformation of the user between an arm part T and a finger part S, and presses the sensor 30 towards the arm part T or the finger part S by the tension being wound around, and is further provided with a display member 200 applying tension to the sensor when a deflection X is generated in the winding-around direction in a state where no tension is applied to the band, and removing the deflection X with the sensor 30 pressed by a pressure capable of detecting the bioinformation.COPYRIGHT: (C)2009,JPO&INPIT【課題】部品点数を少なくすることができ、所定の張力で装着する際に利用者に煩わしさを感じさせないセンサ装着用バンド及び生体情報機器を提供する。【解決手段】伸縮性を有し、利用者の生体情報を検出するセンサ30を腕部Tまたは指部Sとの間に挟み込む態様で巻き付けられ、この巻き付けられた張力によってセンサ30を腕部Tまたは指部Sに押圧するセンサ装着用バンドにおいて、当該バンドに張力が作用していない状態で巻き付け方向に撓みXが生じ、張力を与えてセンサ30が生体情報を検出可能な圧力で押圧される状態で撓みXが解消する表示部材200を備えた。【選択図】図6
