A heat spreader () and a method for manufacturing the heat spreader are disclosed. The heat spreader includes a metal casing () and a wick structure () lines an inner surface of the metal casing. The metal casing defines therein a chamber () and includes an evaporating section () and a condensing section (). The wick structure is in the form of metal foam and occupies a portion of the chamber. In one embodiment, the wick structure has a pore size gradually increasing from the evaporating section towards the condensing section of the metal casing. The heat spreader is manufactured by electrodepositing a layer of metal coating () on an outer surface of a metal foam framework (). The metal coating becomes the metal casing and the metal foam framework becomes the wick structure.
