PROBLEM TO BE SOLVED: To provide a heat insulation door capable of surely spreading a foaming fluid to the foaming fluid flow directional downstream side of a support member and preventing generation of a dent in a door material. SOLUTION: In the support member 26, angles A and B of the upstream side end part 31 and the downstream side end part 32 in the flow direction of an urethane foaming fluid 40 are formed into acute angles, the urethane foaming fluid 40 is divided to the left flow and the right flow by the upstream side end part 31 and flow along both side faces 33 and 34 and downstream side side faces 35 and 36 to converge in the vicinity of the downstream side end part 32. Therefore, the urethane foaming fluid 40 surely spreads to the downstream side of the support member 26, and formation of an air pocket is prevented, so that generation of the dent in the door material 21 for the heat insulation door can be prevented.
