6. A method of manufacturing a light emitting device, comprising the steps of:
-
applying a water-repellent material to a surface of a mounting substrate with a solid-state light-emitting element mounted, on which the solid-state light-emitting element is mounted, so as to surround the solid-state light-emitting element; forming a first resin layer with a dome shape outside the solid-state light-emitting element by applying transparent resin to the outside of the solid-state light-emitting element; and forming a second resin layer with a dome shape outside the first resin layer by applying transparent resin that contains a phosphor which is excited with a luminescence wavelength of the solid-state light-emitting element, to the outside of the first resin layer. - View Dependent Claims (7)

8. A method of manufacturing a light emitting device, comprising the steps of:
-
forming a first resin layer made of transparent resin outside a solid-state light-emitting element mounted on a mounting substrate, by using a mold; and forming a second resin layer made of transparent resin that contains a phosphor which is excited with a luminescence wavelength of the solid-state light-emitting element, outside the first resin layer by using a mold.
