The present invention addresses the problem of obtaining a fluorescent-material-containing resin sheet which exhibits excellent formability, favorable light resistance, and favorable heat resistance, and when used as a light-emitting element, has high brightness and low variation in light emission between chips. As a means of solving this problem, this fluorescent-material-containing resin sheet contains a fluorescent material, a resin, and metal oxide particles (I) having an average particle diameter of 10-200 nm, wherein the amount of the fluorescent material contained therein is 250-1000 parts by mass per 100 parts by mass of the resin. Preferably, this sheet also contains metal oxide particles (II) having an average particle diameter of 300-1000 nm, and as a separate embodiment, preferably contains silicone fine particles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fluorescent-material-containing resin sheet and light-emitting device","description":"The present invention pertains to a fluorescent-material-containing resin sheet to be used as a light-emitting element.
