PROBLEM TO BE SOLVED: To provide a vapor chamber capable of being thinned and superior in strength.SOLUTION: A container 2 is composed of a pair of plate materials 3, 4 jointed to each other at a prescribed interval in which a working fluid is sealed, the lower plate 3 is provided with a projecting portion 6 projecting toward the upper plate 4 and a recessed portion 7 recessed to the upper plate 4 to separate from the upper plate 4 which are formed from a prescribed part where the working fluid is evaporated to another part where the vapor of the working fluid is condensed, a clearance part 10 is formed between the projecting portion 6 and the upper plate 4, the clearance part 10 being a liquid flow channel in which a liquid-phase working fluid 11 is retained by capillary force obtained by forming meniscus by intrusion of the liquid-phase working fluid 11 and allowed to flow, and the recessed portion 7 is a vapor flow channel in which the vapor of the working fluid flows.SELECTED DRAWING: Figure 1 |
