Abstract:
A light emitting device includes an electrically conductive member, a light emitting element, a wire, and a sealing member. The wire contains gold and silver and connects the electrically conductive member and the light emitting element. The wire includes a ball portion and a recrystallized region. The ball portion is provided on an electrode of the light emitting element. The recrystallized region is provided on the ball portion and has a length in a range of 50 μm to 90 μm. The sealing member has a lower surface and an upper surface opposite to the lower surface and covers the light emitting element and the wire so that the lower surface faces the electrically conductive member and the light emitting element and so that a distance from a top of the ball portion to the upper surface of the sealing member is 90 μm to 230 μm.
