PROBLEM TO BE SOLVED: To provide a method for manufacturing a hollow-molded article having through inserts, which can prevent breaking of parisons in insert vacant spaces with no elongation up to adhesion to the inner surface of the inserts to cause an insufficient adhesion of the broken edges to the inner surface of the inserts. SOLUTION: A continuity of the outside of a die to through inserts is cut off at the initial stage of blowing, the continuity is reopened at the intermittent stage of blowing, and then the connection is cut off again at the last stage of blowing, whereby the above problem can be solved.
