Abstract
A biometric information detecting apparatus including: a pair of electrodes coming into contact with a surface of a living body; and a circuit board to which a pair of the electrodes are connected and configured to detect biometric information on the basis of a potential difference generated between a pair of the electrodes, the circuit board including an electrode connecting pattern Co which a pair of the electrodes are electrically connected, and a detection circuit unit configured to detect the biometric information on the basis of the potential difference; and a GND pattern provided on the circuit board between the electrode connecting pattern and the detection circuit unit.
Claims8
A biometric information detecting apparatus comprising:
- a pair of electrodes coming into contact with a surface of a living body;
- and
- a circuit board to which a pair of the electrodes are connected and configured to detect biometric information on the basis of a potential difference generated between a pair of the electrodes, the circuit board including an electrode connecting pattern to which a pair of the electrodes are electrically connected, and a detection circuit unit configured to detect the biometric information on the basis of the potential difference;
- and
- a low potential pattern set to have a potential lower than that of the electrode connecting pattern provided on the circuit board between the electrode connecting pattern and the detection circuit unit.
