Abstract

This invention relates to a silicone material satisfying any of the following conditions in an elemental composition percentage of the silicone material surface according to X-ray photoelectron spectroscopy (ESCA): (i) the elemental composition percentage of carbon atoms is from 50.0 to 70.0 atom%; (ii) a ratio of the elemental composition percentage of carbon atoms to the elemental composition percentage of silicon atoms (C/Si) is from 2.0 to 5.0; or (iii) both of the above conditions (i) and (ii). The silicone material is stable against light and heat, in which a decrease in transmittance and generation of cracks do not tend to occur.
