PROBLEM TO BE SOLVED: To provide an inner door for a vending machine that can improve separability and can reduce the number of parts while maintaining heat insulation performance. SOLUTION: The vending machine inner door 18 comprises outlet doors 20 for closing an article outlet normally and opening the article outlet when an article is dispensed from an article storage part, outlet door frames 21 made of resin mounted with the outlet doors 20, an inner door body 22 made of a resin sheet provided with the outlet door frames 21 at a lower end and forming an outer frame of the inner door, and a heat insulator 23 formed by the injection of a foaming agent into an internal space defined by the outlet door frames 21 and inner door body 22. The resin sheet forming the vending machine inner door body 22 and the foaming agent injected into the internal space defined by the inner door body 22 to form the heat insulator 23 can provide an excellent heat insulation effect and can dispense with separation for disposal to improve separability.
