To provide a panel loading method for easily loading an inner panel to an outer panel having a bent portion formed by bending the periphery thereof without degrading the accuracy of hemming, and to provide a panel-loading support device.

The outer panel having the bent portion formed by bending the periphery thereof and the inner panel are overlapped to be integrated at the periphery. For this purpose, the panel loading method for loading the inner panel to the outer panel includes: a step where at least one of the outer panel and the inner panel is provided by an elastic body and the outer panel is disposed onto a panel receiver so that the bent portion is directed upward; a step where a guide plate is placed on the bent portion; a step where the inner panel is loaded to the outer panel from above the guide plate and a step where the inner panel is inserted into the inside of the bent portion of the outer panel.
