PROBLEM TO BE SOLVED: To firmly fix a frame and a flat plate material in simple constitution and reduce waste and its disposing cost. SOLUTION: A sliding door is formed by a flat plate material 22 and a frame 24 disposed in the outer periphery of the flat plate material 22. The frame 24 is provided with a groove part 25 opened inward to allow the outer edge part of the flat plate material 22 to fit therein, and a projecting piece 34 projected from the inside wall 25a of the groove part 25 into the groove and pressed when the flat plate material 22 fits in to be elastically deformed. When the flat plate material 22 fits in the groove part 25, an air layer 36 is formed between the projecting piece 34 closely adhering to the flat plate material 22 and an inside wall 25a of the groove part 25. The frame 24 is formed of a hard resin, the projecting piece 34 is formed of a soft resin, and these are integrally formed.
