To provide an interior panel with a lighting window, in which the lighting window can be easily formed.

An interior panel with a lighting window enables the lighting window to be easily formed by combining a surface material 2, a pedestal member 3 and a translucent window member 4. The assembly becomes easier because of a composition of a flexible part (clearance). As a space part has a ventilation under the same condition as outdoor air, the lighting window does not mist by condensation and others. Thus the lighting window can be seen as continuously extending in a thickness direction of the interior panel due to a visual effect.
