Abstract
A method of manufacturing a light-emitting device includes: mounting a light-emitting element on a mounting board; placing a light-shielding frame on a sheet, the light-shielding frame defining an opening and comprising at least one narrow portion having a width that is smaller than that of another portion of the light-shielding frame in a top view; applying a light-reflective resin on at least the narrow portion of the light-shielding frame; forming a light-guiding supporting member; and bonding the second surface of a light-transmissive member of the light-guiding supporting member to an upper surface of the light-emitting element so as to fix the light-guiding supporting member on or above the light-emitting element.
