Abstract
A sensor () is configured such that a seal member () is provided in a deformed manner through crimping of a portion of a tube () located toward a rear end () of the tube (). The seal member () is deformed such that a frontward-oriented surface (), which is a bottom surface of a recess () formed in a front end () of the seal member (), presses a rear end () of an insulation sheath () frontward. Consequently, a front end () of a sensor element is pressed against a front end () of the tube () via the insulation sheath (). By virtue of a pressing action induced by rubber-like elasticity, high sensor responsiveness is maintained over a long period of time.
