| Zusammenfassung: | An object would be to propose an infrared detector capable of reducing occurrence of false detection due to flow of gas. The infrared detector (100) includes: an infrared sensor (2); a circuit board (111); a cover (7); and an infrared transmitting member (3). The circuit board (111) includes a front surface (1111) and the infrared sensor (2) is mounted on the front surface (1111). The cover (7) faces the front surface (1111) of the circuit board (111) and includes an exposing hole (70) exposing the infrared sensor (2). The infrared transmitting member (3) covers the exposing hole (70). The circuit board (111), the cover (7), and the infrared transmitting member (3) form an accommodation space (S10) enclosing the infrared sensor (2) therein. |
