Method of manufacturing light emitting device and light emitting device
A method of manufacturing a light emitting device includes providing an intermediate body having a light emitting element, a bottom part on which the light emitting element is disposed, and a first wall disposed on the bottom part and surrounding the light emitting element apart from a lateral face of the light emitting element. The method further includes disposing a light transmissive member having a height in excess of the height of the first wall and covering the upper face of the first wall and the light emitting element, forming a first groove by removing a portion of the light transmissive member thereby exposing at least a portion of the upper face of the first wall, forming a second wall by disposing a first resin in the first groove, and cutting the second wall along a lengthwise direction of the first groove thereby obtaining the light emitting device.
