To provide a solid-state light-receiving device for ultraviolet light which can measure the amount of irradiation with ultraviolet light harmful to the human body using a simplified structure and properly and accurately, which can be readily integrated with a sensor of a peripheral circuit, which is small, light-weight, and low-cost, and which is suitable for mobile or wearable purposes. One solution is a solid-state light-receiving device for ultraviolet light which is provided with a first photodiode (1), a second photodiode (2), and a differential circuit which receives respective signals based on outputs from these photodiodes, wherein a position of the maximum concentration of a semiconductor impurity is provided in each of the photodiodes (1,2) and in a semiconductor layer region formed on each photodiode, and an optically transparent layer having a different wavelength selectivity is provided on a light-receiving surface of each photodiode.
