Abstract
An object of the present invention is to provide a method of forming a hollow blow-molded foam and also provide such a hollow-molded foam, which are capable of improving a flow-rate efficiency of a fluid that flows through the inside of the hollow blow-molded foam. A foaming resin is sandwiched between molds so that a hollow blow-molded foam having a ventilation path is molded, and a fluid for use in cooling the hollow blow-molded foam is allowed to flow through the ventilation path so that the hollow blow-molded foam is cooled.
