Method for manufacturing an optical module and optical module

A method for manufacturing an optical module, comprising:

• 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 sealing the surface of the board including lateral faces, a top face, and a lower face of the light emitting device with a first light transmissive resin mixed with a light wavelength conversion material;
• a step of covering a top surface of the first light transmissive resin with a second light transmissive resin;
• a step of funning 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 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 resin;
• and
• a step of dicing the light emitting device by cutting along the light reflective resin such that outer peripheral lateral surface is covered with the light reflective resin by leaving part of the light reflective resin filled in the groove.

An optical module, comprising:

• a board having a plurality of electrodes on its surface;
• a light emitting device mounted on the plurality of electrodes of the board in a facedown manner;
• a resin sheet containing a light wavelength conversion material provided above the light emitting device;
• a first light transmissive resin sealing a space between the board and the resin sheet including a space between the light emitting device and the resin sheet;
• a second light transmissive resin covering a face of the resin sheet opposite to the face of the resin sheet sealed with the first light transmissive resin;
• and
• a light reflective resin containing a light reflective material provided to cover an outer peripheral lateral surface along the outer peripheral lateral surface of a stack constituted of the board, the light emitting device, the resin sheet, the first light transmissive resin and the second light transmissive resin.
