Abstract

A method for manufacturing a light emitting device includes preparing a light transmissive member block including a first light transmissive member block having a plate like shape and including a resin containing at least one phosphor and a second light transmissive member block including a material harder than a material of the first light transmissive member block. Grooves are formed on an upper face of the second light transmissive member block. The light transmissive member block is divided at the grooves to obtain a plurality of light transmissive members each having a first light transmissive member and a second light transmissive member. A lower face of the first light transmissive member and an upper face of a light emitting element are bonded together such that a lower face perimeter of the first light transmissive member is located outside of an upper face perimeter of the light emitting element.
