Semiconductor light-emitting device and method for manufacturing the same

A semiconductor light-emitting device comprising:

• a base including a base obverse surface and a base reverse surface spaced apart from each other in a first direction, including a pair of first side surfaces spaced apart from each other in a second direction perpendicular to the first direction, and including a pair of second side surfaces spaced apart from each other in a third direction perpendicular to the first direction and the second direction;
• a semiconductor light-emitting element mounted on the base obverse surface;
• a light-transmitting sealing resin covering the semiconductor light-emitting element and having a smaller dimension than the base as viewed in the first direction;
• a wiring pattern electrically connected to the semiconductor light-emitting element and including an obverse surface electrode formed on the base obverse surface;
• and
• an insulating resist layer including a pattern-covering portion overlapping with the obverse surface electrode as viewed in the first direction,
• wherein the pattern-covering portion includes a resin outflow preventing portion, and as viewed in the first direction, the resin outflow preventing portion is disposed outside the resin sealing part and extends continuously from one of the paired second side surfaces to the other one of the paired second side surfaces.
