A air pad for biological information detection includes a air bag set underneath a person whose biological information is detected so that it crosses in the direction of the height of such person. The air pad also includes the first and the second air tube located in the longitudinal direction of the air bag and an internal air tube set inside the air bag, and connected to the second air tube as well as stretches from the second air tube toward the other side of the longitudinal direction of the air bag.生物資訊檢測用之氣墊,其具備有:空氣袋,其被配置在生物資訊之檢測對象者之下方,與該檢測對象者之身高方向產生交叉;第1及第2空氣管,其等皆被設置在上述空氣袋之長邊方向之一端側,且其兩端分別被配置在上述空氣袋之外部及內部;及內部空氣管,其被設置在上述空氣袋之內部,且被接合至上述第2空氣管,並且自該第2空氣管而延伸至上述空氣袋之長邊方向的另一端側。10‧‧‧生物資訊檢測裝置50‧‧‧氣墊感測器51‧‧‧氣墊52a‧‧‧空氣管52b‧‧‧空氣管53‧‧‧內部空氣管54‧‧‧黏接部55‧‧‧黏接部60‧‧‧空氣合流部61a‧‧‧橡膠管61b‧‧‧橡膠管62‧‧‧空氣合流構件63‧‧‧橡膠管70‧‧‧本體部
