Abstract
A temperature sensor including a temperature sensing element () having a temperature sensing unit () and a pair of device electrode wires () extending from the temperature sensing unit; a sheath member () including a sheath wire () connected at a junction () to one of the device electrode wires and a sheath outer pipe () retaining the sheath wire in an insulating material (); an inner tube () which has a bottomed cylindrical shape, the inner tube accommodating the temperature sensing element and the junction in a bottom portion side of the inner tube serving as a leading end of the temperature sensor, and extending in an extension direction of the device electrode wire and the sheath wire; and an outer tube () which has a bottomed cylindrical shape including a gas inlet hole (), the outer tube covering the inner tube, and being spaced, from the inner tube on a leading end side of the junction when viewed in a direction perpendicular to an axial direction of the inner tube.
