Claim 0:
1. A vapor chamber comprising: a container in which a cavity portion is formed in an inside; a wick structure provided in the cavity portion; a working fluid enclosed in the cavity portion; a vapor flow path which is formed in the cavity portion and through which the working fluid in a gas phase flows; and a hydrogen occlusion metal that is disposed in the cavity portion and absorbs hydrogen at 350° C. or lower and does not release hydrogen at 350° C. or lower,
the hydrogen occlusion metal being coated in a region in contact with the working fluid in an inner surface of the cavity portion and/or the wick structure,
wherein the container is a planar container that is formed by one plate-shaped body and another plate-shaped body facing the one plate-shaped body,
the hydrogen occlusion metal is disposed in a section where the working fluid condenses,
the wick structure is provided in a plurality of rows and extends in a fence-shaped manner, and the wick structure is interposed between a plurality of protruding portions of the other plate-shaped body and the one plate-shaped body to be fixed in the container, but no wick structure is provided between the plurality of protruding portions,
the hydrogen occlusion metal is provided in the entire cavity portion or in a section of the cavity portion that is other than an evaporation portion and includes a condensation portion,
a ratio of a thickness of the vapor flow path directly above the coating of the hydrogen occlusion metal to a thickness of the coating of the hydrogen occlusion metal is 0.50 or greater and 20 or lower, and
both the hydrogen occlusion metal and the wick structure are provided on an inner surface of the one plate-shaped body.
