Document Type and Number:
WIPO Patent Application WO/2020/196587
Kind Code:
A1
Abstract:
[Problem] To provide an electrode having excellent sensitivity and an electrochemical measurement system. [Solution] A carbon electrode 1 according to the present invention is provided with: a base material 2; and a conductive carbon layer 3 that is arranged on one side of the base material 2 in the thickness direction and has an sp2 bond and an sp3 bond. In one surface of the conductive carbon layer 3 in the thickness direction, the concentration ratio of oxygen to carbon, namely O/C is 0.07 or less.
