HEAT TRANSPORT DEVICE AND METHOD OF MANUFACTURING TRANSPORT DEVICE

To provide a heat transport device that can suppress a gap from being formed where adjacent plate-like members are welded together to improve bending strength of the plate-like members, and improve flatness of the plate-like members to reduce heat resistance between a heating element and the plate-like members.SOLUTION: A container 10 consists of a plurality of plate-like members 11, 12 which are stacked, and the plurality of plate-like members 11, 12 have abutting parts 11b, 12b that the mutually adjacent plate-like members 11, 12 abut on respectively on outer edge parts 11a, 12a thereof. The plurality of plate-like members 11, 12 which are stacked have a separation part 10a where opposed faces of the mutually adjacent plate-like members 11, 12 are separate on at least one of outer peripheral sides and inner peripheral sides of the abutting parts 11b, 12b, wherein the abutting parts 11b, 12b have fixed parts 11b1, 12b1 which are fixed by welding, and support parts 11b2, 12b2 which are provided at positions adjoining the fixed parts 11b1, 12b1, and support the adjacent plate-like members 11, 12, respectively.SELECTED DRAWING: Figure 3 【課題】隣り合う板状部材同士が溶接される部分における隙間の発生を有効に抑制し、板状部材の曲げ強度を向上させるとともに、板状部材の平坦度を向上させて発熱体と板状部材との間の熱抵抗の低減を図ることのできる熱輸送デバイスを提供する。【解決手段】コンテナ１０は、積層される複数の板状部材１１、１２からなり、複数の板状部材１１，１２は、それぞれの外縁部１１ａ，１２ａにおいて、互いに隣り合う板状部材１１，１２が当接する当接部１１ｂ，１２ｂを有し、積層された複数の板状部材１１，１２は、当接部１１ｂ，１２ｂの外周側および内周側の少なくとも一方において、互いに隣り合う板状部材１１，１２同士の対向する面が離間する離間部１０ａを有し、当接部１１ｂ，１２ｂは、それぞれ、溶接によって固定される固定部分１１ｂ１，１２ｂ１と、固定部分１１ｂ１，１２ｂ１に隣接した位置に設けられ、隣り合う板状部材１１，１２を支持する支持部分１１ｂ２，１２ｂ２と、を有している。【選択図】図３
