Abstract
An image reading apparatus includes an image reading chip for reading an image. The image reading chip includes a plurality of pixel units which include a light receiving element which receives light from the image so as to perform photoelectric conversion, an analog circuit, a logic circuit, and a power source pad to which a power source voltage is supplied. The image reading chip has a shape which includes a first side and a second side shorter than the first side. A distance between the analog circuit and a median point of the first side is shorter than a distance between the logic circuit and the median point of the first side, and a distance between the analog circuit and the power source pad is shorter than a distance between the logic circuit and the power source pad.
