Abstract
A method for manufacturing a light-emitting element includes removing a resin layer of a multilayer composite by thermal decomposition. The multilayer composite includes a luminescent layer containing a plurality of luminescent particles, the resin layer disposed on the luminescent layer, and a light reflection layer disposed on the resin layer. The resin layer contains a solid resin and a plurality of resin particles dispersed in the solid resin. A temperature at which the reduction in mass of the resin particles measured by thermogravimetric analysis reaches 70% is lower than a temperature at which the reduction in mass of the solid resin measured by thermogravimetric analysis reaches 70%.
