PROBLEM TO BE SOLVED: To provide a light-emitting diode element in which a light-emitting diode such as a near-ultraviolet LED and a white LED is sealed, and the adhesion between the light-emitting diode and the sealant is good, and the sealant is deteriorated by long-term use. A primer is provided for the light-emitting diode element which is difficult. SOLUTION: At least a part selected from the group consisting of (A) a silane coupling agent, a hydrolyzate thereof, and a condensate of the hydrolyzate, and (B) inorganic oxidation on at least a part of the surface of the light emitting diode element. A light-emitting diode having a primer layer made of a cured product of the composition cured on the surface of the light-emitting diode sealing primer composition characterized by containing a product particle An element is obtained, and then the light emitting diode element is sealed with a sealant.
