An apparatus includes: a first heat generating component; a second heat generating component arranged close to the side of the first heat generating component; a heat radiating member that absorbs heat from both the first heat generating component and the second heat generating component and radiates heat. The heat radiating member includes: a base section that extends horizontally and contacts the first heat generating component on the bottom surface of the base section; and a pair of arms that extend horizontally at both ends of the base section, have a fastener for fastening the heat radiating member, and contact the second heat generating component under one of the pair of arms.
