Abstract
A detecting element () of a gas sensor () is held with a detecting portion () projecting from a front-end engaging-portion () of a metallic shell () and is accommodated for protection in an inner protector () in a gas detection chamber (). Exhaust gas introduced into the gas detection chamber () is exhausted through an exhaust hole (). The exhaust hole is formed by cutting off a portion of a side wall () of a recess portion (), which is formed by pressing inward a portion between two slits formed in a front end wall (). A bottom wall () of the recess portion () is located frontward of the detecting element () with respect to the direction of an axis O, thereby preventing a water droplet which comes flying from the outside from directly contacting the detecting element ().
