Abstract
A semiconductor light-emitting device includes: a printed-wiring board; a light-emitting diode element mounted on the printed-wiring board; and a resin body for sealing the light-emitting diode element. The resin body is composed of a first resin body arranged around the light-emitting diode element, and a second resin body, which seals the light-emitting diode and the first resin body. An upper edge of the first resin body disposed at a lower position of the PN-junction is configured to be at least on or beyond an imaginary line that connects the PN-junction and a lower edge of the second resin body.
