Abstract

The vapor chamber includes a casing, a working fluid, a microchannel, and a wick. The casing includes an upper casing sheet and a lower casing sheet that face each other and are joined together at an outer edge so as to define an internal space therebetween. The working fluid is sealed in the internal space. The microchannel is in the lower casing sheet and in communication with the internal space so as to form a flow path for the working fluid. The wick is in the internal space of the casing, and is in contact with the microchannel. An area of the wick is larger than an area of a region corresponding to the microchannel in a plan view of the vapor chamber.
