Abstract
An electrochemical sensor unit including: a working electrode; and a counter electrode, wherein the working electrode includes a diamond film which generates a redox reaction on a surface when a voltage is applied between the working electrode and the counter electrode, and a support which is formed of a material different from diamond and supports the diamond film, when the working electrode is viewed laterally, in the support, a width of a surface opposite to a surface in contact with the diamond film is smaller than a width of the diamond film, and a liquid test sample is supplied to the working electrode from the diamond film side.
