To provide a method for fitting a product with a mount such as a calendar on the mount which enables quick and efficient fitting of the product on the mount and is thus suitable for mass production and which enables exact fitting of the product at a prescribed position of the mount.

A small hole 5 opening to the surface side from the rear side is bored beforehand in the mount 1, at the fitting position of the product such as the calendar 2, and a hot-melt adhesive 6 or the like in a molten state is applied to a portion where the small hole 5 is provided in the rear of the mount 1, in a state wherein the back of the product is brought into contact with the surface of the mount 1. By making the adhesive 6 penetrate into the small hole 5 of the mount 1 and making it stick to the back of the product, the mount 1 and the product are adhered to each other.
