  • Publication number: 20220190556
    Abstract: A semiconductor light emitting device includes a substrate, a common conductive portion formed on the substrate, a semiconductor light emitting element mounted on the common conductive portion, and an electronic component mounted on the common conductive portion and electrically connected to the semiconductor light emitting element by the common conductive portion. This structure shortens the conductive path between the semiconductor light emitting element and the electronic component, thereby reducing capacitance caused by the conductive path between the semiconductor light emitting element and the electronic component. Thus, while reducing parasitic capacitance, the semiconductor light emitting element and the electronic component are electrically connected.
