PROBLEM TO BE SOLVED: To improve precision of sensing and warning, by expanding the degree of freedom of an installation place of a sensor. SOLUTION: This sensor 16 for sensing the temperature, smoke or a flame is arranged inside a door body 3, and a sensing hole is arranged on the obverse-reverse surfaces of the door body 3 corresponding to a sensing part of the sensor 16 so that the sensor 16 can sense the temperature, the smoke or the flame of a room positioned on both sides of a door 1. The door 1 can be used as a door of an opening part arranged in an individual house, a multiple dwelling house or a building and a store, a door used for an ancillary facility such as a closet (a storage), a vestibule storage, the other storage and a face washing dressing table, and a door such as furniture and a utensil.
