PROBLEM TO BE SOLVED: To provide a biological information detector capable of preventing a failure due to a current applied to between a pair of electrodes even if moisture permeates in a detection circuit board.SOLUTION: The biological information detector includes the pair of electrodes each contacting the surface of a living body, and a circuit board 12 causing the pair of electrodes to be connected thereto and detecting biological information on the basis of a potential difference between the pair of electrodes. In the detector, an electrode connection pattern 18 for causing the pair of electrodes to be electrically connected thereto, and a detection circuit unit 19 for detecting the biological information based on the potential difference are provided on the circuit board 12. On the circuit board 12, GND patterns 20a, 20b are provided between the electrode connection pattern 18 and the detection circuit unit 19.COPYRIGHT: (C)2013,JPO&INPIT【課題】検出回路基板に水分が浸入した場合であっても、一対の電極間に電流が流れて不具合が生じてしまうことを防止できる生体情報検出装置を提供する。【解決手段】生体表面に接触する一対の電極と、これら一対の電極が接続され、一対の電極の間に生じる電位差に基づいて、生体情報を検出する回路基板12とを備え、回路基板12上に、一対の電極が電気的に接続される電極接続パターン18と、電位差に基づいて、生体情報を検出する検出回路部19とが設けられている生体情報検出装置であって、回路基板12上には、電極接続パターン18と検出回路部19との間に、GNDパターン20a,20bが設けられている。【選択図】図7
