| 1. A semiconductor light emitting device comprising:
a semiconductor laminated body including a light emitting layer and having a light extraction surface for light emitted from
the light emitting layer, the light extraction surface being substantially flat;
a conductive film provided on the light extraction surface of the semiconductor laminated body and being translucent to the
light emitted from the light emitting layer; and
an electrode provided above the conductive film,
the conductive film covering substantially all of the light extraction surface,
a bottom surface of the conductive film being flat,
the conductive film having a thicker portion and a thinner portion provided on the light extraction surface,
a top surface of the thicker portion being substantially flat,
a top surface of the thinner portion being substantially flat, and
a step being formed on a surface of the conductive film between the thicker portion and the thinner portion.
