Abstract: Provided is a heat sink where the formation of a boundary layer on surfaces of heat radiating fins is suppressed so that portions other than on the windward side along the cooling air flow can also exhibit excellent heat radiation property.The heat sink includes: a base plate; a first heat radiating fin thermally connected to the base plate; and a second heat radiating fin disposed adjacently to a side end portion of the first heat radiating fin, and thermally connected to the base plate, wherein a surface of the first heat radiating fin is not parallel to a surface of the second heat radiating fin, and at least one of the second heat radiating fins is disposed at a position lower than at least one of the first heat radiating fins in a vertical direction with respect to a front surface of the base plate.

Abstract: The invention provides a flattened heat pipe whose vapor flowing passage is not clogged and which has an excellent capillary force. The flattened heat pipe has a closed container formed by flattening a tubular container, a plurality of wick structures arrayed within the container in a longitudinal direction so as to form an acute-angled portion where a capillary force is large at least partially within the container, a hollow portion formed of an outer peripheral surface of the wick structure and an inner wall surface of the container and a working fluid sealed into the container.
