An imaging apparatus includes: a duct; a fan that generates a flow of air in the duct; first, second, and third cooling targets; a first heat sink that absorbs heat of the first cooling target and includes first fins exposed in the duct; a second heat sink that absorbs heat of the second cooling target and includes second fins exposed in the duct; and a third heat sink that absorbs heat of the third cooling target and includes third fins exposed in the duct. The first, second and third fins extend in different directions from one another, as viewed in a direction of the flow of air in the duct, as far as each of the fins gets close to another fin with a predetermined distance apart.
