Abstract

An InGaN-based light-emitting diode that emits light in blue, for example, is mounted on a support substrate as a semiconductor light-emitting element, and a transparent film is fixed to the support substrate so as to cover the semiconductor light-emitting element. An electrode pattern is formed on an upper surface of the transparent film, and the electrode pattern is electrically connected to terminal electrodes of the semiconductor light-emitting element through, for example, through-holes. The transparent film can contain a phosphor excited by light emitted from the semiconductor light-emitting element. It is not necessary to perform wire bonding for connecting the semiconductor light-emitting element to the electrode pattern and sealing with a sealant.
