Patent ID: 7728283

Claim:
An illuminance detecting component, comprising: a supporting substrate comprising: a substrate body made of silicon; and pads provided on an upper surface of the substrate body; a plurality of light receiving elements connected electrically to the pads and receiving light irradiated from an outside, said plurality of light receiving elements being arranged in array fashion on the upper surface side; external connection terminals connected electrically to the light receiving elements; and a translucent member provided on the substrate body, wherein an airtight space in which the plurality of light receiving elements are accommodated is formed between the translucent member and the substrate body; and wherein each of the plurality of light receiving elements has a light receiving portion for receiving said light, and a light shielding member for shielding the light is provided on a first surface of the translucent member opposing the light receiving elements, and openings for passing the light are provided at locations of the light shielding member in one-to-one correspondence with the light receiving elements and opposing the light receiving portions, such that portions of the light shielding member cover portions of the light receiving elements and each of the openings is aligned with a respective said light receiving portion, and vice-versa, in one-to-one correspondence, as viewed from the outside in a direction normal to the light receiving elements, and each of the openings is smaller than an area of its said respective light receiving portion, so that the portions of the light shielding member cover the light receiving elements and portions of the light receiving portions except for areas of the light receiving portions that are exposed to the openings.
