Abstract: A method for manufacturing a light-emitting module includes: providing a wiring substrate including: a base member having an upper surface, and a metal layer disposed on the upper surface of the base member; forming a resist layer on the wiring substrate such that the metal layer is exposed from the resist layer; disposing an intermediate body on the resist layer, the intermediate body comprising a light-emitting element and a covering layer; forming a bonding member; removing the resist layer and the covering layer; and forming a plating layer on a surface of the bonding member by plating, such that a portion of the plating layer is located between an electrode surface of the light-emitting element and the bonding member.

Abstract: A light emitting element has first and second electrodes. In plan view, the first electrode has a first connecting portion, a first extending portion, and two second extending portions. The second electrode has a second connecting portion, and two third extending portions. The first extending portion extends linearly toward the second connecting portion, and the second extending portions are arranged on two sides of the first extending portion. The second extending portions each has two bent portions and a linear portion extending parallel to the first extending portion and disposed between the two bent portions. The third extending portions extend parallel to the first extending portion between the first extending portion and the second extending portions. The second extending portions extend beyond the second connecting portion. The first and second connecting portions are symmetrically arranged with respect to a virtual line parallel to one side of the light emitting element.

Abstract: A light emitting element has first and second electrodes. In plan view, the first electrode has a first connecting portion configured to be bonded with a conductive wire, a first extending portion, and two second extending portions. The second electrode has a second connecting portion configured to be bonded with a conductive wire, and two third extending portions. The first extending portion extends linearly toward the second connecting portion, and the two second extending portions are arranged on two sides of the first extending portion. The second extending portions each has two bent portions and a linear portion extending parallel to the first extending portion and disposed between the two bent portions. The third extending portions extend parallel to the first extending portion between the first extending portion and the second extending portions. Each of the second extending portions extends beyond a position of the second connecting portion.
