PROBLEM TO BE SOLVED: To easily attain the insertion and hold of a conductor by providing a rear conductor passage faced to the conductor passage of a terminal hardware to a base body, and forming the deep side of the rear conductor passage as a tapered part whose top end is made narrow. SOLUTION: A terminal hardware is provided with a conductor passage, a base main body 2 is provided with rear conductor passages 8a and 8b faced to the conductor passage, and the deep sides of the rear conductor passages 8a and 8b are formed as a tapered part 8c whose top end is made narrow. At the time of mounting a conductor on the terminal part of the base of this fire sensor, when the top end part of the conductor is inserted into a front conductor passage 7a, the top end part of the conductor is allowed to move straight while a restraining piece is pressurized, and to reach the rear conductor passage 8a. At that time, the conductor is allowed to move forward while the bending of the conductor to an adjacent front conductor passage 7b side is restrained by a release button, and the top end part of the conductor is allowed to abut to a tapered wall face 8t of the terminal tapered part 8c, and to move forward along the taper wall face 8t. Then, the top end part of the conductor is introduced to a prescribed position, and the top end is exposed.
