Semiconductor light emitting device and lead frame

A semiconductor light emitting device comprising:

• a lead frame;
• a chip mounted on the lead frame, the chip including a substrate and a light emitting element provided on the substrate;
• a wall section including an inner wall facing to a side portion of the chip, and an outer wall on an opposite side to the inner wall;
• and
• a phosphor layer provided on the chip within a range of an inside area of the inner wall of the wall section, the phosphor layer being thinner than the chip,
• a distance between the side portion of the chip and the inner wall of the wall section being smaller than a thickness of the chip.

A lead frame comprising:

• a first lead frame including:
• an inner lead section continuous in a first direction;
• and
• a plurality of outer lead sections integrally provided to the inner lead section, and separated in the first direction from each other;
• and
• a second lead frame separately provided in the first direction with respect to the first lead frame.
