Abstract: A light detection device includes a semiconductor substrate, a signal detection light receiving portion, and an infrared light receiving portion. First and second color filters cover the signal detection light receiving portion and the infrared light receiving portion, respectively. The first color filter passes therethrough visible light in a first wavelength range as well as infrared light. The second color filter passes therethrough visible light in a second wavelength range as well as infrared light. A third color filter covers the infrared light receiving portion. The third color filter passes therethrough visible light in a third wavelength range different from the second wavelength range as well as infrared light. An infrared cut filter covers the signal detection light receiving portion and has an opening in a region opposite to the infrared light receiving portion.

Abstract: An object of the present invention is to provide a method by which hydrogen peroxide can be produced at a satisfactory level from an industrial and economical viewpoint without causing the load of purification to be large and without needing too large facilities for production. The present invention is directed to a method for producing hydrogen peroxide, which comprises reacting hydrogen and oxygen in a reaction medium in the presence of a noble metal catalyst and a radical scavenger.
