A photo detection device includes a first lead frame, a second lead frame, a photo detection die having a coating layer, and an enclosure. The first lead frame forms a carriage section. The coating layer is formed on the photo detection die. The photo detection die is mounted on the carriage section of the first lead frame and forms electrical connection with the second lead frame through a conductor. The enclosure is a non-light-transmittable member forming therein a receiving space. The enclosure is mounted on the first and second lead frames and receives the photo detection die in the receiving space thereof. The enclosure forms an opening for light detection by the photo detection die. As such, detection of a long wavelength invisible light, such as an infrared light, by the photo detection die can be prevented to thereby provide a photo detection device with increased reliability of detection.
