PURPOSE: To make the thickness of a resin hollow container with permeability resistance be a specified thickness, improve the dimensional precision, make fabricating and elimination of chips accompanied with the fabricating easier, and shorten the cycle time in the manufacture process.
CONSTITUTION: The resin hollow container A is constituted of a pair of divided bodies 1, 1 which consist of an inner surface member 3 made of a resin, a permeation preventive film 4 to prevent permeable substances from permeating, which is laminated on the outside of said inner surface member 3, and an outer surface member 6 made of a resin, which 18 laminated on the outside of the permeation preventive film 4. The peripheral edges of the pair of divided bodies 1, 1 are welded to each other.
