PROBLEM TO BE SOLVED: To provide thermal insulation panels which can be installed quickly at a low cost, of which heat shielding performance can be maintained for a long time, which can be carried and stored in a flatly placed state, and can be easily assembled to a box shape on the construction site without using any supporting members and can be laid in a self-standing state. SOLUTION: A turned down line 40 for a side standing wall is formed at the end portion in an axial direction of a flat cylindrical body 3 by doubly piling upper and lower sheet members 10 and 20; a bending formation is performed from the turn-down line for the side standing wall by which an upper surface wall 41, a lower surface wall 42 and right and left side standing walls 43, 43 are formed; at least one surface of the inner surface is formed in a manner permitting the assembly to a cylindrical body 4 with a rectangular section as a low emissivity surface; a turned-down line 5 for a standing wall at the end portion is formed at the front and rear end portions of the upper and lower seat member; bending formation is made from the turned-down line for the end standing wall; an end standing wall 50 is provided at the end surface of the front and rear opening end surface of the cylindrical body 4 with rectangular sections; and it is formed in such a manner that the assembling can be possible to a box-shaped panel 6 having an air gap in the inside.
