To provide a manufacturing method of a decorative sheet-pasted inorganic panel capable of pasting up a decorative sheet by the reduced number of manufacturing processes.

A cementitious molding material, which comprises a cement-containing inverse emulsion composition based on cement, water and an oily substance containing at least one of styrene and methyl acrylate, is molded into a panel shape. Then, the panel-shaped molded object 1 is aged/cured in a state that the decorative sheet 2 based on an aromatic compound is laminated to the back of the panel-shaped molded object 1. When the panel-shaped molded object 1 is aged, styrene or methyl methacrylate in the cementitious molding material acts on the decorative sheet 2 comprising the material based on the aromatic compound to bond and paste up the decorative sheet 2 simultaneously with the aging/curing of the panel-shaped molded object 1.
