An LED module includes: a substrate including main, rear, and bottom surfaces; a first light emitting element disposed on the main surface; a conductive layer formed on the substrate and electrically coupled with the first light emitting element; a first conductive bonding layer interposed between the first light emitting element and the conductive layer; a main surface insulating film formed on the main surface and covering a portion of the conductive layer; and a first wire, wherein the main surface and the rear surface face opposite directions, the bottom surface connects long sides of the main and rear surfaces, the conductive layer includes a first wire bonding portion where the first wire is bonded, and the main surface insulating film includes a first insulating portion including a portion interposed between the first light emitting element and the first wire bonding portion when viewed in a thickness direction of the substrate.
