Patent ID: 8884329

Claim:
A semiconductor light-emitting element comprising: a first semiconductor layer that has a first conduction type; a light-emitting layer that emits light by current flow and is laminated on the first semiconductor layer; a second semiconductor layer that has a second conduction type and is laminated on the light-emitting layer; a conductive layer that has conductivity and is laminated on the second semiconductor layer; a first metal layer that is composed of a metallic material containing Au and is laminated on the conductive layer; and a second metal layer that is composed of a metallic material containing Au and having an indentation hardness lower than an indentation hardness of the metallic material composing the first metal layer, the second metal layer being laminated on the first metal layer so that a surface thereof opposite to another surface contacting the first metal layer is exposed to outside, wherein the first metal layer comprises a plurality of crystal grains of a columnar structure and the second metal layer comprises a plurality of crystal grains of a random cluster shape, and the average size of the crystal grains of the first metal layer is larger than the average size of the crystal grains of the second metal layer.
