Abstract: A method includes mounting a light emitting device on a board having electrodes on its surface, disposing a resin sheet containing a light conversion material so as to face the surface of the board and filling a space between the resin sheet and the board with a first light transmissive resin, covering a surface of the resin sheet opposite to a surface of the resin sheet covered with the first light transmissive resin, with a second light transmissive resin, forming a groove extending from a top surface of the second light transmissive resin to the board, filling the groove with light reflective resin and covering the top surface of the second light transmissive resin with the light reflective resin, removing the light reflective resin, and dicing the light emitting device by cutting along the light reflective resin.

Abstract: A method for manufacturing an optical module includes a step of mounting a light emitting device on a board having a plurality of electrodes on its surface in a facedown manner, a step of disposing a resin sheet containing a light conversion material so as to face the surface on which the light emitting device is mounted of the board and filling a space between the resin sheet and the board including the resin sheet and the light emitting device with a first light transmissive resin, a step of covering a surface opposite to a surface of the resin sheet covered with the first light transmissive resin with a second light transmissive resin, a step of forming a groove extending from a top surface of the second light transmissive resin to a predetermined depth of the board, a step of filling the groove with the light reflective resin and covering the top surface of the second light transmissive resin with the light reflective resin, a step of removing the light reflective resin on the second light transmissive re

Abstract: An optical module includes a wiring substrate; an optical element mounted on the wiring substrate; a first light-transmitting body mounted on an upper surface of the optical element; and a light-shielding resin covering the optical element and a side surface portion of the first light-transmitting body, wherein the light-shielding resin includes filler, an upper surface of the light-shielding resin is a ground surface, and a ground surface of the filler is exposed on the upper surface of the light-shielding resin.
