Zusammenfassung:	A vapor chamber that includes a housing having a first sheet and a second sheet that oppose each other and are joined to each other in a peripheral region of the housing, a working liquid in an internal space of the housing, a wick structure on a principal surface of the first sheet that opposes the second sheet, and multiple pillars on a principal surface of the second sheet that opposes the first sheet. In the vapor chamber, the first sheet includes an inclined portion that is disposed along at least part of the peripheral region of the housing and is inclined in a height direction toward a joint portion with the second sheet. In addition, a first portion of the second sheet at the joint portion heightwise overlaps a second portion of the second sheet in a second region in contact with the pillars.
