PROBLEM TO BE SOLVED: To suppress reduction in heat insulation performance of a vacuum insulation material in a heat insulation container using the vacuum insulation material.SOLUTION: A plurality of L-shaped panels 22, which are made of a vacuum heat insulation material and are formed in an L shape in a plane view, are provided inside an outer box 11. The L-shaped panels 22 comprise two flat panel parts 24 which are continuous through corner parts 23 formed in a round shape. At a contact portion between the L-shaped panels 22, a free end surface 25 of the flat panel part 24 of one L-shaped panel 22 comes into contact with an inner surface of the flat panel part 24 of the other L-shaped panel 22. A foam pressing part 32 is formed between an outer surface, which is a surface on the opposite side from the flat panel part 24 with respect to the inner surface in the contact portion, and a wall part of the outer box 11. The inner surface is pressed against the free end surface 25 when the foam pressing part 32 foams. Foam corner parts 33 are formed on the inner surface side and the outer surface side of the corner 23.SELECTED DRAWING: Figure 1 |
