Abstract: A gas sensor element having a chamfered portion. The chamfered portion has a leading end chamfered portion formed in a leading end portion of the gas sensor element, a rear end chamfered portion formed in a rear end portion of the gas sensor element, and an intermediate chamfered portion linking the leading end chamfered portion and rear end chamfered portion. The chamfer angle of the rear end chamfered portion is formed so as to be larger than the chamfer angle of the leading end chamfered portion.
