Zusammenfassung:PURPOSE: A thermosetting resin composition is provided to give good thermosetting properties without the use of a curing accelerator and to reduce the discoloration of a resin under conditions of high temperature or light with high energy for a long time. CONSTITUTION: The thermosetting resin composition comprises an epoxy-containing resin and a curing agent, wherein the curing agent is cyclohexanetricarboxylic acid and/or anhydrides thereof, and wherein the mixing ratio of the epoxy-containing resin to the curing agent is 0.1-3.0 as an equivalent ratio expressed as (X/2)Y, wherein X is the total equivalent number of carboxyl groups when an acidic anhydride group is estimated into 2 as the equivalent number of a carboxyl group, and a carboxyl group is estimated into 1 as the equivalent number of a carboxyl group, and Y is the number of epoxy groups in the resin.
