Carrier, carrier leadframe, and light emitting device

A carrier, comprising:

• two electrode portions, each having an electrode portion cross section;
• and a housing, having a housing cross section and covering at least a part of the electrode portion, wherein the housing cross section is not level with the electrode portion cross section, the housing and electrode portion cross sections having been formed during production of the carrier by removing steps in which residual material of a plastic body forming the housing and parts of extending portions forming the electrode portions are removed, and wherein the housing comprises a plurality of concave portions formed between a side surface and a bottom surface of the housing resulting from a mechanical engagement between the concave portions and respective supporting portions of a frame body in a state where electrode portions of different carriers of a leadframe are electrically isolated from each other;
• wherein the electrode portion cross section comprises an antioxidant layer;
• wherein a portion of the electrode portion cross section uncovered with the antioxidant layer is integrally formed with a central area of an electrode portion of the two electrode portions.
