DOOR

PROBLEM TO BE SOLVED: To provide a door which is mass produced simply and easily at low cost, in which the boundary between a surface plate and a frame member is finished beautifully in an ideal state, a thin plate member used for a surface plate is firmly fixed to the frame material so as not to be separated therefrom to reliably and beautifully secured to the frame member in a structure preventing the frame member from protruding from the surface place. SOLUTION: The door has the side edges of the surface plate 1 secured to both surfaces of the frame member 3. The surface plate 1 has a bend connection piece 7 having the side edges secured to the frame member 3 bent inside the door. The frame member 3 has, on both surfaces, a fitting groove 8 into which the bend connection piece 7 of the surface plate 1 is inserted in the longitudinal direction. The door has the bend connection piece 7 of the surface plate 1 inserted into the fitting groove 8 of the frame member 3, causing the surface plate 1 to be adhered to the frame material 3 and secured on both surfaces of the frame member 3.
