Claim Text:
1. A semiconductor light emitting device comprising: a semiconductor layer including a first semiconductor layer having a first conductivity type, a second semiconductor layer having a second conductivity type, and a light emitting layer provided between the first semiconductor layer and the second semiconductor layer; an electrode pad provided in adjacent to the semiconductor layer; a first electrode connected to the electrode pad with one end, extending from the electrode pad, and being connected on one surface of the first semiconductor layer; a second electrode connected to the second semiconductor layer; a layer provided between part of the first semiconductor layer and part of the first electrode and having conductivity less than conductivity of the first electrode; a first insulating layer provided between the first electrode and the second electrode; the first electrode having an electrode width, the electrode width being a length along a surface that the first electrode connects to the first semiconductor layer, the length being in a direction perpendicular to a direction in which the first electrode extends, the electrode width decreasing with distance from the electrode pad, the first electrode being in contact with a first surface of the first semiconductor layer, the first surface being a surface on a side where the light emitting layer is provided, the layer being contact with the first surface and extending from an edge of the electrode pad along the direction in which the first electrode extends, the first electrode including a first portion that is contact with the first surface and provided in adjacent to the layer, and a second portion that is contact with the layer at a side facing away from a surface of the layer that is contact with the first surface, the second portion extending from the edge of the electrode pad along the direction in which the first electrode extends, a substrate having conductivity; and a conductive layer provided between the second electrode and the substrate, and provided on the first portion and the second portion through the first insulating layer, the conductive layer being in contact with a surface of the second electrode and electrically connecting to the second electrode and the substrate.
