To facilitate finishing work by providing a method for manufacturing a hollow elastic article which will be hardly damaged even by giving an impact.

Split elements 11, 11 made of a semispherical cup-like body 11 and a shaft 112 projected from a center of an outer surface of a bottom of the body 111 are combined in a hollow shape, held in a mold cavity by the shaft 112, and a continued surface layer 2 made of a rubber-like elastic material is molded so as to cover a hollow core 1 made of the elements 11, 11. A protrusion 112a of the end of the shaft 112 projected from the layer 2 is cut and removed.
