Abstract
A high-pressure hydrogen container includes: a cylinder body; and a lid member that closes an end portion of the cylinder body. The cylinder body includes: a joining portion that fixes the lid member; a cylinder portion that forms an outer shell of a storage portion; and a sealing surface formed at an inner surface of the cylinder body. At least H<K is satisfied, where an area of the sealing surface which the sealing portion abuts is an abutting area, H is a thickness from the abutting area to an outer surface of the cylinder body, part of the cylinder body in which a stress greater than or equal to a predetermined stress σ is generated is a stress generation portion, and L is a distance between the abutting area and the stress generation portion.
