PROBLEM TO BE SOLVED: To provide a door easily and efficiently assemblable without installing core materials at specific positions relative to frames by adopting a simple beautiful design without clearances on its front surfaces. SOLUTION: This door is so formed that surface plates 1 are secured to its both surfaces and decorative plates 4 are secured to opening windows 2 opened in the surface plates 1 through the frames 3 to close the opening windows 2. The surface plates 1 on both surfaces are so formed that the inner peripheral edge inner surfaces of the opening windows 2 are cut off, cut parts 6 are formed along the inner peripheral edge parts, and the thickness of the inner peripheral edges of the surface plates 1 is made smaller than the overall thickness of the surface plates 1. The frame 3 is so formed that its inner shape is positioned along the inner shape of the opening window 2, and projected line parts 11 guided by the cut parts 6 of the surface plates 1 are formed along the inner peripheral edges of the outer surfaces. Further, the decorative plate 4 and the frames 3 are formed in an integral frame unit 15 by inserting the outer peripheral edge of a decorative plate 4 into the recessed groove 14 formed in the inner surface of the frame 3. The door fixes the decorative plate 4 and the frames 3 between the surface plates 1 on both sides in the state of the frame unit 15 in which the decorative plate 4 is fixed to the frames 3.
