A heat dissipation plate has a structural body including a first metal portion formed from a first metal and a second metal portion formed from a second metal that differs from the first metal and bonded to the first metal portion through solid state bonding. The first metal has a higher thermal conductance than the second metal, and the second metal has a higher mechanical strength than the first metal. The structural body includes a first surface of the heat dissipation plate connected to a semiconductor element and a second surface of the heat dissipation plate located at a side opposite to the first surface. The second surface includes an upper surface of the first metal portion and an upper surface of the second metal portion.

A heat sink may include: a flat plate portion; a first protruding portion which is formed on an outer peripheral portion of the flat plate portion so as to surround a central portion of the flat plate portion and which protrudes in a thickness direction of the flat plate portion; an extending portion which extends outward from the flat plate portion; and a second protruding portion which is formed on the extending portion such that the first protruding portion is positioned between the second protruding portion and the central portion of the flat plate and which protrudes in the thickness direction of the flat plate portion.

A heat-radiating component is bonded via a thermal interface material (TIM) to an electronic component (chip) mounted on a wiring board. The heat-radiating component includes a plate-like portion thermally bonded to the chip through the TIM, and a foot portion formed on a surface which faces the electronic component, of the plate-like portion. The foot portion is formed in a ring shape at a position which surrounds a region corresponding to a mounting area of the electronic component, on the inner side of the periphery of the plate-like portion.
