PROBLEM TO BE SOLVED: To easily recover an electric conducting function without requiring the exchange of an electrocardiograph itself even when the electric conducting function is deteriorated by the attachment of dust, scurf, or a gel agent to be used for adhesion to a human body, etc., in the connection part of an electrode or by the breakage of a connection structure, and also to attain further lightweight and compactness together with waterproof property, vibration resistance and external pressure resistance strength in order to contribute to regular wearing.SOLUTION: A physical information recorder includes: biological electrodes 1 used for adhesion to a human body to acquire electric signals for physical information and a recorder 2 recording the electric signals from the biological electrodes 1 as physical information. The recorder 2 includes: a storage part 30 for storing a battery and a battery storage lid 31 arranged to be removable from the storage part 30. The storage lid 31 includes: a first electric connection part with the biological electrodes 1 and second electric connection parts with the storage part 30. The electric signals acquired from the biological electrodes 1 are transmitted to the recorder 2 via the first electric connection part and the second electric connection parts.COPYRIGHT: (C)2013,JPO&INPIT【課題】電極の接続部にゴミや垢、あるいは身体貼り付けに使用するゲル剤等が付着したり、接続構造が破損したりして電気導通機能が劣化した場合であっても、心電計自体の交換を要することなく容易に電気導通機能を回復し得ると共に、常時装着の用に供するべく防水性、耐振動性、耐外圧強度と共に一層の軽量化、小型化を可能とする。【解決手段】身体に貼り付けて身体情報用の電気信号を取得する生体電極1と、生体電極1からの電気信号を身体情報として記録する記録装置2とを具備するものであって、記録装置2は、電池を収容する収容部30と、収容部30から取り外し可能に設けられた、電池の収容蓋31とを備え、この収容蓋31は、前記生体電極1との第一電気接続部、及び収容部30との第二電気接続部を備え、生態電極1から取得された電気信号は、第一電気接続部、第二電気接続部を介して記録装置2に伝達される。【選択図】図2
