Provided is a combination smoke and heat detector which allows, in spite of a simple structure, light emitted from an indication lamp to be visually confirmed from a wide range of directions. A combination smoke and heat detector (100) includes a body base (10), a printed circuit board (1), a thermosensitive element (2), a dark chamber (3), an indication lamp (4) mounted to the printed circuit board (1), a protective cover (30), and a bar-like light guide (5) for guiding light emitted from the indication lamp (4) to outside of the protective cover (30). The light guide (5) passes through a light guide through-hole (35) formed in the protective cover (30) so as to be mounted therein, with one end surface thereof being faced with the indication lamp (4), and another end surface thereof protruding to the outside of the protective cover (30) by a height substantially equal to or larger than a protruding height of the dark chamber (3). Further, the light guide (5) is arranged oppositely to the thermosensitive element (2), with the dark chamber (3) being sandwiched therebetween.
