Claim 20:
21. A light-emitting device comprising:
a package comprising:
a light-emitting element comprising a first surface and a second surface opposite to the first surface;
a first light-transmissive member arranged on the second surface of the light-emitting element;
paired electrodes at the first surface of the light-emitting element; and
a first covering member covering the light-emitting element such that the paired electrodes are exposed from the first covering member;
a light-guiding plate on which the package is placed;
a second covering member arranged on the light-guiding plate and covering laterally the package; and
paired wirings continuously covering the paired electrodes exposed and the first covering member and being connected to the paired electrodes respectively, the paired wirings comprising a mixture of a resin and metal powder,
wherein a part of the first covering layer arranged between the paired electrodes is removed, and
wherein at least one groove between the paired electrodes has a width of 10 μm to 100 μm and a depth of 0.1 μm to 3 μm.
