PROBLEM TO BE SOLVED: To provide a manufacturing process of a panel object which can suppress the secular degradation of a solar radiation reflectance factor to low by a simple manufacturing process, and the panel object. SOLUTION: An organic-inorganic component gradient composition type coating film 2 is formed on the surface of a metal-made panel object base material 1 by baking, and a photocatalyst layer 3 containing an anatase-type titanium oxide is formed on the upper surface of this formed organic-inorganic component gradient composition type coating film 2 by baking. Here, the surface mean roughness Ra of the formed organic-inorganic component gradient composition type coating film 2 is preferably 6μm or more to 14μm or less, and the surface mean roughness Ra of the photocatalyst layer 3 containing an anatase-type titanium oxide is preferably 7μm or more.
