To provide a folding screen which can suppress the weight over the entire part and has a structure capable of securely fixing hinges without dislodgment even if brittle plate materials like plate materials made of foamed resins are used and to provide the hinges which are light in weight and are easily produced.

This folding screen has at least two sheets of the plate materials made of the foamed synthetic resins and the hinges which are formed of one sheet of the synthetic resin sheet and are bendable to a dog leg shape. The one peak surface of each hinge is stuck by an adhesive to the end face of the one plate material and the other peak surface is stuck by the adhesive to the end face of the other plate material, by which the freely oscillatable connection of the plate materials with the hinges is made possible.
