Abstract:
This optical sensor device includes a first light receiving portion having sensitivity to ultraviolet light, a first sealing portion covering the first light receiving portion, a second light receiving portion having sensitivity to ultraviolet light, and a second sealing portion which covers the second light receiving portion. At least one of the first sealing portion and the second sealing portion is configured to transmit at least part of a ultraviolet light wavelength band, the first sealing portion is formed from one or more resin layers and has transmission spectral characteristics that a first wavelength is set as a lower limit value of a transmission wavelength band, and the second sealing portion is formed from one or more resin layers and has transmission spectral characteristics that a second wavelength different from the first wavelength is set as a lower limit value of the transmission wavelength band.
