Abstract:
1. An optical-semiconductor device comprising a substrate, an optical-semiconductor element on the substrate, a compression molded body comprising a two-step cured encapsulating resin layer comprising a condensation-addition curing type silicone resin in an amount of 50% or more of components constituting the encapsulating layer, and a wavelength conversion layer containing light wavelength-converting particles, wherein the wave conversion layer is laminated directly or indirectly on said encapsulating resin layer, the encapsulating resin layer embeds the optical-semiconductor element, the wavelength conversion layer is not present in a side surface of said molded body, and the optical-semiconductor device satisfies the following formulae (I) and (II) when a thickness of the encapsulating resin layer is regarded as (X) (mm), an area of the sheet for optical-semiconductor element encapsulation necessary for encapsulating one optical-semiconductor element is regarded as (Y) (mm
