A multi-sensor comprises: a smoke chamber for sensing smoke by detecting a scattered light with a light detecting portion, the scattered light being generated by the smoke which enters the smoke chamber to scatter a light emitted from a light emitting portion; a heat sensing element for sensing heat, which is provided above the smoke chamber; and an insert portion which constitutes a wall body having a hole for inserting a wire of the heat sensing element; wherein the wall body is approximately consecutive from an upper surface of an inside of the smoke chamber to a lower surface of an inside of the smoke chamber, and the hole penetrates through the upper surface to the lower surface, to an outside of the smoke chamber. <IMAGE> |
