PURPOSE: To obtain an artificial tree having a trunk composed of resin- impregnated hollow braided fiber ropes fixed to a fiber-reinforced plastic pipe, produced by using a resin material vanishing with time as a part of the trunk, usable as a substitute for a cut tree and spontaneously weathering according to the growth of a seedling.

CONSTITUTION: A tree-constituting unit 7 is produced by integrally fixing resin- impregnated hollow braided fiber ropes 6 to the outer circumference of a resin- reinforced plastic pipe 5. A plurality of the units 7 are bundled with a ring- shaped clamping member 8 to form a trunk 2. Branches 3 made of resin- impregnated rod-shaped fiber materials are fixed to the trunk 2 with the ring- shaped clamping member 8. The branch is furnished with artificial leaves 4 made of a fiber material such as synthetic resin to obtain an artificial tree 1. A resin material vanishing by weathering (e.g. a photo-degradable plastics) is used as at least a part of the trunk 2 of the artificial tree 1. The obtained artificial tree is spontaneously weathered according to the growth of seedlings.
