PROBLEM TO BE SOLVED: To provide a biological information detecting device capable of preventing occurrence of failure in an electrical connection part while securing excellent maintainability, and capable of preventing the detection capability from becoming unstable.SOLUTION: The biological information detecting device includes: a body part a heart rate detection part 3 integrated with the body part and having electrodes 6a and 6b to be brought into contact with a living body surface and a fixing band, detachably attached to the body part, for attaching the body part and the heart rate detection part 3 to a users body. The body part and the heart rate detection part 3 are integrated with each other via a mechanical connecting projection 41 for mechanically connecting the body part and the heart rate detection part 3 and via an electrical connection part 44 for electrically connecting the body part 2 and the electrodes 6a and 6b of the heart rate detection part 3. The relative positional relationships between the mechanical connection projection 41 and the electrical connection part 44 are set so as not to be disposed side by side in the direction of loading of external force applied to the mechanical connecting projection 41.COPYRIGHT: (C)2013,JPO&INPIT【課題】良好なメンテナンス性を確保しつつ、電気的接続部に不具合が生じることを防止すると共に、検出性能が不安定になることを防止することができる生体情報検出装置を提供する。【解決手段】本体部と、この本体部と一体的に設けられ、生体表面に接触する電極6a,6bを有する心拍検出部3と、本体部に対して着脱自在に設けられ、この本体部、及び心拍検出部3を身体に装着するための固定バンドとを備え、本体部と心拍検出部3は、これらを機械的に接続する機械的接続凸部41と、本体部2と、心拍検出部3の電極6a,6bとを電気的に接続する電気的接続部44とを介して一体的に設けられており、機械的接続凸部41と電気的接続部44の相対位置関係は、機械的接続凸部41にかかる外力の荷重方向に沿って並んで配置されないように設定されている。【選択図】図4
