摘要

Provided are a method and product for producing a hollow molded product by which a hollow molded product having an extremely thin uniform thickness can be produced easily, efficiently, and stably. Disclosed is a method for producing a hollow molded product comprising a spraying step for forming a resin layer by spraying a liquid resin having a potential difference relative to a die on the inside of the die which can be divided into two or more parts using a spraying tool inserted through a mouth of the die; a solidifying step for solidifying the resin layer; a releasing step for opening the die relative to the spraying tool, and releasing the solidified resin layer from the die while holding the resin layer by the spraying tool; and a removing step for removing the resin layer held by the spraying tool from the spraying tool.
