PROBLEM TO BE SOLVED: To provide a vending machine capable of maintaining excellent heat-insulating performance and suppressing increase in manufacturing cost at the same time. ! SOLUTION: A heat-insulating warehouse 8 provided in a vending machine main body is divided into a plurality of heat-insulating chambers 12 (12A, 12B), and both side faces and a back face of each heat-insulating chamber are surrounded by a heat insulating partition wall 10 provided in the heat-insulating warehouse 8 and a heat-insulating side wall of the heat-insulating warehouse 8. The heat-insulating partition wall 10 is constituted of a heat-insulating material 20E with no spaces provided for the heat-insulating side wall arranged on the back face of the heat-insulating warehouse 8. The heat-insulating side wall is constituted such that a plurality of a vacuum heat-insulating materials 20 (20B, 20E) is superposed each other so that a part thereof forms a double portion in the thickness direction, and a part on which the vacuum h |
