The present invention provides a catalytic conversion-type sensor that detects a detection target gas by detecting a conversion gas produced through a reaction, the catalytic conversion-type sensor including: a gas flow path that allows the detection target gas to flow down; and a conversion portion that is connected to the gas flow path, the conversion portion including, on a side partitioned by a diffusion means that allows the detection target gas to naturally diffuse, a heated catalyst portion that produces a conversion gas by causing the detection target gas to come into contact with a heated catalyst and react with the heated catalyst, and a sensor element portion that is capable of detecting the conversion gas produced through the reaction.

Catalytic-conversion-type sensor

A controlled potential electrolysis gas sensor including, as gas electrodesfor detecting gas, a working electrode for electrochemically reacting gas to be detected, a counter electrode with respect to the working electrode, and a reference electrode for controlling potential of the working electrode, the gas electrodesbeing disposed to face an electrolysis solution accommodating portion of an electrolysis tank accommodating electrolytic solution. Each electrodeincludes a noble metal catalyst layer. On the noble metal catalyst layerof at least one of the working electrode and the reference electrode, there is formed a polymer layerhaving ion conductivity and water permeability.
