<p>Provided is a gas sensor capable of reliably securing and protecting a ceramic member inside a casing. An oxygen sensor (1) is provided with: a cylindrical detection element (6); a main bracket (5) for holding the detection element (6); a terminal bracket (70) which is electrically connected to the detection element (6); a lead line (18) extending from the terminal bracket (70) and forming a current path; a separator (8) through which the lead line (18) is inserted; an inner cylinder (3) surrounding the separator (8); a grommet (9) arranged in the cylinder hole of the inner cylinder (3), the lead line (18) being inserted through the grommet; a filter (7) arranged on the outside, in the radial direction, of the inner cylinder (3); and an outer cylinder (100), the filter (7) being positioned between the outer cylinder and the inner cylinder (3). The separator (8) is sandwiched by the detection element (6) and the grommet (9), and thereby held in a state of being set apart from the inner cylinder (3).</p> |
