Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat insulating panel, maintaining the interior of an airtight space in a pressure reduction state, with a flexibility by providing a covering body formed that a heat insulating material is arranged in an airtight space surrounded with a covering material having airtightness and flexibility. SOLUTION: A plurality of grooves 1a are formed in juxtaposition at least in one side part of a covering substance 6 and an airtight space 9 is filled with inorganic powder P serving as a heat insulation material 2. In manufacture of the heat insulation panel, before the heat insulation material 2 is arranged in a covering space 8, the inorganic powder P is contained in a bag body 5 having permeability. The bag body 5 containing the inorganic powder P is nipped between a pair of upper and lower molding dice 10 at least in one of which a plurality of protrusions 11 are previously formed in juxtaposition to mold a pressure powder molded product 2A. The molded pressure powder molded product 2A forms the heat insulating material 2 of a heat insulating panel.
