PROBLEM TO BE SOLVED: To provide a polymerizable monomer giving a resin with a good refractive index without using inorganic oxide fine particles and heavy atoms, and a heat-resistant resin composition with a high refractive index obtained by using the polymerizable monomer. SOLUTION: The polymerizable monomer having 1,3,5-triazine ring represented by formula (1) is provided. In formula (1), one or two of A<SP>1</SP>to A<SP>3</SP>are each -N(R<SP>1</SP>)CH<SB>2</SB>-CH=CH<SB>2</SB>group or -O-CH<SB>2</SB>-CH=CH<SB>2</SB>group, and the reminder thereof is -N(R<SP>2</SP>)(R<SP>3</SP>) group or a specific nitrogen-containing heterocyclic group.
