PROBLEM TO BE SOLVED: To provide a hard coat layer-coated material showing outstanding properties such as impact resistance together with hardness by setting the ratio of a silicon atom and a carbon atom at a specific value, when the composition of the hard coat layer applied on the surface is measured using an X-ray electrospectrometry. SOLUTION: A hard coat layer showing outstanding hard coat properties is applied on the surface of each of various kinds of an object. The ratio of a silicon atom and a carbon atom in the hard coat layer (Si/C) is set to be 0.1-10.0. The ratio of Si and C in the hard coat layer can be set by an X-ray electrospectrometry. When the ratio of Si/C is less than 0.1, this means that the Si content of the hard coat layer is at a low level. Thus the dense polysiloxane part of a polymer forming the hard coat layer is reduced so that the hard coat properties are not developed. In addition, the performance such as wear resistance, impact resistance or durability of the hard coat layer is not enhanced. When the ratio of S/C is 10.0 or over, the polysiloxane part containing the Si is in excess, so that the hard coat layer is brittle.
