In a gas sensor (100), a base end portion (175b) of a second outer wall (175) of an outer protector (171) is airtightly connected to a forward end portion (164c) of a first inner wall (164) of an inner protector (161). The outer protector (171) has a taper wall (172) which is located on the axially forward end side of the second outer wall (175). The taper wall (172) has the shape of a tapered tube whose diameter decreases toward the axially forward end side, and has a second outer hole (176), which is a forward end opening. The entire taper wall (172) is disposed on the axially forward end side in relation to the inner bottom wall (162) of the inner protector (161). |
