To provide a fitting of a novel configuration, which is implemented by throwing away a conventional fixed concept that double glazing is set in an opening section in order to ensure the heat insulation of the same.

There is provided an entrance door 1 which is formed of an outside panel 10, an inside panel 11, first and second apertures 12, 13 penetrating between the outside panel and inside panel, and a facing panel 14 mounted on the outside panel 10. The entrance door 1 is further formed of a first outside shielding member 2 for shielding the outside of the first aperture 12, a first inside shielding member 3 for shielding the inside of the aperture 12, a first outside casing 4 for supporting a rear surface of the first outside shielding member 2 and almost flatly mounting the first outside shielding member 2 on the facing panel 14, and a first inside casing 5 for supporting a rear surface of the first inside shielding member 3 and almost flatly mounting the first inside shielding member 3 on the first inside panel 11. Further the second aperture 13 has almost the same configuration as that of the first aperture 12.
