摘要： In an electrochemical gas sensor (10), a first sensing element (21) is stored in a first storage portion (31). A moisture permeable film (24) is disposed in a first introduction inlet (31A) of the first storage portion (31). The moisture permeable film (24) substantially prevents a to-be-detected gas from permeating therethrough. A second sensing element (22) is disposed in a space into which water vapor and the to-be-detected gas contained in a target gas flow. In such a configuration, the electrochemical gas sensor (10) is capable of detecting a to-be-detected gas having a concentration of 0 or more and 1 ppm or less.

摘要： A spark plug wherein least one of a center electrode and ground electrode includes a shaft portion and an electrode tip joined to one surface of the shaft portion. The shaft portion includes a first core formed of a material containing copper and a first outer layer that is formed of a material having higher corrosion resistance than the first core and covers at least part of the first core. The electrode tip includes a second outer layer that is formed of a material containing a noble metal and forms the outer surface of the electrode tip and a second core that is formed of a material having a higher thermal conductivity than the second outer layer and is at least partially covered with the second outer layer.
