Abstract: To provide an antifouling article having an antifouling layer formed on the surface of an organic material using a fluorinated compound, wherein the antifouling article is excellent in antifouling properties and has durability such as abrasion resistance with respect to the antifouling properties.An antifouling article comprising: a substrate, at least a portion of the surface thereof being made of an organic material; a primer layer disposed on the surface made of the organic material; and an antifouling layer disposed on the primer layer; wherein: the primer layer is a layer formed by using a first silane compound which has a hydrolyzable silyl group, and a reactive organic group (a reactive organic group (A)) that is a group having a linking group and a reactive group, or a reactive group other than a hydrolyzable group; the absolute value of the difference between the SP value of the organic material and the SP value of the reactive organic group is from 0 to 3.0 (J/cm3)1/2; and the antifouling layer is a layer formed by using a second silane compound having a perfluoropolyether group and a hydrolyzable silyl group.

Abstract: A light-emitting device 1 comprises a base 30, a nitride semiconductor light-emitting element 10 flip-chip mounted on the base 30, and an amorphous fluororesin sealing the nitride semiconductor light-emitting element 10. The light-emitting device 1 comprises a deformation-prevention layer 60 for preventing a shape change of an amorphous fluororesin by heat treatment after shipment of the light-emitting device 1, and the deformation-prevention layer 60 is formed of a layer in which a thermosetting resin or an ultraviolet curing resin is cured, and the cured layer directly covers the surface of the amorphous fluororesin.
