特徴とするスモーク濃度検知器。A smoke sensor equipped with a heat-resistant insulator with a pair of electrodes formed on one end of its surface and a heater is attached to the exhaust pipe by fixing it inside a hollow metal holder serving as a member, and detecting the smoke concentration of the hollow metal boulder. In a smoke concentration detector in which a bottomed hollow metal foot having a ventilation hole is fixed to the electrode side end of the element, all of the ventilation holes are sometimes installed on the front surface opposing the exhaust flow when attached to the exhaust pipe. A smoke concentration detector characterized by:
