Image reading apparatus and semiconductor device

An image reading apparatus comprising:

• an image reading chip that reads an image,
• wherein
• the image reading chip includes
• a first pixel unit that includes a first light receiving element configured to receive light from the image and perform photoelectric conversion, and generates a first pixel signal,
• a second pixel unit that includes a second light receiving element configured to receive light from the image and perform photoelectric conversion, and generates a second pixel signal,
• a first amplification unit that is electrically connected to the first pixel unit, amplifies the first pixel signal, and outputs a first amplification signal,
• a second amplification unit that is electrically connected to the second pixel unit, amplifies the second pixel signal, and outputs a second amplification signal, and
• a third amplification unit that amplifies each of the first amplification signal and the second amplification signal, and outputs an amplified signal,
• the image reading chip has a shape which includes a first side and a second side shorter than the first side, and
• the third amplification unit is disposed between the first amplification unit and the second amplification unit in a direction along the first side.
