Claim:
1. A heat-receiver, comprising: a first plate portion that receives heat at a first face from a heat generating body; a second plate portion facing a second face of the first plate portion, and having a greater plate thickness than a plate thickness of the first plate portion; at least one first coupling portion that couples together the first plate portion and the second plate portion; a second coupling portion that thermally couples together the first plate portion and the second plate portion, wherein said second coupling portion is positioned to correspond to a central portion of the heat generating body, with the first plate portion being between the second coupling portion and the heat generating body; and a gap between the second coupling portion and the at least one first coupling portion through which a coolant passes in a direction, wherein the second coupling portion has a width along the second face of the first plate portion that is greater than a width of each of the at least one first coupling portions, as viewed along the coolant passing direction, and wherein a thermal capacity of the second coupling portion is greater than a thermal capacity of each of the at least one first coupling portions.
