Abstract
A sensor body of an electrochemical gas sensor having no water reservoir is housed in a metal can including a sensing electrode on one surface of a proton-conducting membrane or a separator retaining an electrolyte and a counter electrode on the opposite surface thereof. The counter electrode is supported by and electrically connected to the metal can via a connecting member. The sensing electrode is connected to a diffusion control plate with the sensing electrode-side ring member, and the ring member is conductive and includes a hole at a center thereof that is connected to a hole of the diffusion control plate.
