Abstract
A sulfurization detection sensorcomprises: a rectangular parallelepiped insulation substrate, a pair of front electrodesprovided at both ends of a front surface in the longitudinal direction of the insulation substrate, respectively, a sulfurization detection conductorconnected between the front electrodes, a pair of protective filmsfor covering a part of the sulfurization detection conductorand that of the front electrodes, respectively, a pair of back electrodesprovided at both ends of a back surface in the longitudinal direction of the insulation substrate, respectively, a pair of end face electrodesprovided at both ends in the longitudinal direction of the insulation substrate, respectively, and external electrodesprovided on front surfaces of the end face electrodes, respectively. Specific regionsin which a current hardly flows are formed at both ends in the Y-direction of a sulfurization detection portionA.
