Gas sensor, and gas sensor manufacturing method |
摘要 |
A gas sensor (1) comprising: a gas detecting element (2) extending in an axial direction and including a detecting electrode (31) provided on an outer surface of a leading end side of the gas detecting element (2), and a lead portion connecting to the detecting electrode (31) and extending toward a rear end side of the gas detecting element (2); a cylindrical metal shell (5) housing the gas detecting element (2) such that the gas detecting element protrudes from a leading end side of the metal shell (5); a powder layer (10) filling a gap between the gas detecting element (2) and the metal shell (5) and covering at least a portion of the lead portion; and an insulating layer (40) provided between the powder layer (10) and the lead portion (32). Also disclosed is a method for manufacturing the gas sensor (1) which includes forming the insulating layer (40) by at least: applying a glass paste; drying the glass paste; and heat-treating the glass paste. |
