Abstract: A vapor chamber includes a housing including first and second sheets that face each other and that include respective outer edge portions joined to each other, supports that support the first and second sheets from inside and that are disposed therebetween, and a hydraulic fluid enclosed in the housing. The first and second sheets do not include an angled portion having an angle of about 90° or less between a joint and a support nearest to the joint. The expression 0.02≤b/a≤0.3 is satisfied, where a is a distance from an outer edge of the outermost support to an inner edge of the joint between the first and second sheets, and b is a distance between the first and second sheets at the outer edge of the outermost support.
