Abstract: PROBLEM TO BE SOLVED: To join together an inner box and a partition wall through a simple structure and a simple method, to improve the structural strength of a heat insulation box body, and to reinforce heat insulation ability. SOLUTION: This heat insulation box body is formed such that through-holes 20, 21, and 24, 25 are formed in both sides and the back of the groove part of an inner box 14 and both sides and the back of a partition wall 15, and the internal part of the partition wall 15 and a space part between an outer box 13 and the inner box 14 are filled with a foaming heat insulation material 16 by using the through-hikes 20 and 24 on both sides as an inflow hole for a foaming heat insulation material 16 and through-holes 21 and 25 in the back as an air vent hole to join together the inner box 14 and the partition wall 15.
