Document Type and Number:
WIPO Patent Application WO/2022/113485
Kind Code:
A1
Abstract:
A gas sensor 1 according to the present invention comprises: a gas sensor element 22; a box-like casing 3 comprising a wall part 3B1 having a gas introduction opening 3B2; a circuit substrate 4 that has a mounting surface 4a upon which the gas sensor element 22 is mounted and is disposed inside the casing 3 such that the gas sensor element 22 and the gas introduction opening 3B2 overlap in a condition in which the mounting surface 4a has been separated from the wall part 3B1; and an annular elastic seal 5 that is formed on the mounting surface 4a so as to surround the gas sensor element 22 and is disposed between the mounting surface 4a and wall part 3B1. The elastic seal 5 comprises a condensation silicone resin that does not include sulfur.
