Semiconductor light-emitting element, electrode and manufacturing method for the element, and lamp

A semiconductor light-emitting element comprising a substrate, a laminated semiconductor layer comprising a light-emitting layer formed on the substrate, one electrode formed on an upper surface of the laminated semiconductor layer, and another electrode formed on an exposed surface of the semiconductor layer, from which the laminated semiconductor layer is partially cut off;

• wherein at least one of the one electrode and the other electrode comprises a junction layer and a bonding pad electrode formed to cover the junction layer,
• the bonding pad electrode has a maximum thickness that is larger than the maximum thickness of the junction layer, and is composed of one or two or more layers,
• slopes, which are made gradually thinner toward an outer circumference, are formed in outer circumference portions of the junction layer and the bonding pad electrode,
• a transparent electrode is formed between the one electrode and the upper surface of the laminated semiconductor layer or between the electrode and the exposed surface of the semiconductor layer,
• a junction recess portion is provided on an upper surface of the transparent electrode, and
• the junction recess portion is covered by the junction layer.
