To provide a heat insulation interior member which can maintain the high heat insulation performance over a long period, is excellent in the productivity, handleability and reliability, is free from maintenance and is light-weight, and provide a manufacturing method of the heat insulation interior member and a vehicular ceiling material having the heat insulation interior member.SOLUTION: A heat insulation interior member 20 comprises: a first vacuum heat insulation material 27; a second vacuum heat insulation material; and a foamed body 23. The first vacuum heat insulation material 27 and the second vacuum heat insulation material are sealed in an outer bag in a decompressed manner such that a core material molded body molded with a core material including an inorganic powder body is surrounded by the outer bag. The foamed body is integrally laminated so as to cover the first vacuum heat insulation material 27 and the second vacuum heat insulation material.SELECTED DRAWING: Figure 3
