摘要：There are provided a foaming filler member which allows, even when the innerspace of a hollow member has a protruding space, easy filling of the protruding spacewithout using an extra member, a heat-foamable sheet used for the foaming fillermember, a method for manufacturing the heat-foamable sheet, and a method for fillingthe inner space of the hollow member. A heat-foamable sheet which extends in onedirection when heated at 100 to 130° C. for 20 minutes and has an extension ratio of 5 to50% in the extension direction is manufactured by stretch-forming a heat-foamablematerial. Even when the inner space has the protruding space, the protruding space canbe easily filled at low cost without using an extra member by using the heat-foamablesheet as the foaming filler member, disposing the foaming filler member in the mainspace of the inner space, and foaming it such that the extending direction of the heat-foamable sheet is oriented toward the protruding space.
