Patent ID: 8440478

Claim:
A manufacturing method for manufacturing a light emitting device comprising a light emitting element; a first resin mold body having an external side surface and provided with a concave portion having a circular shape or ellipsoidal shape in plan view at a center of the first resin mold body; a plurality of lead frames arranged on a bottom surface of the concave portion and electrically connected to the light emitting element; and a second resin mold body made of a second thermosetting resin filled in the concave portion, wherein the light emitting element is placed on the lead frame and a surface of the second resin mold serves as a light emitting surface, the manufacturing method comprising steps of: a first process for sandwiching the lead frames by an upper die, which is provided with a protruding portion to be contacted with the lead frames and used for forming the concave portion, and a lower die paired with the upper die; a second process for injecting a first thermosetting resin into a space formed by the upper die and the lower die toward a normal line direction of a circular cross section or ellipsoidal cross section of the protruding portion; a third process for heating up the injected first thermosetting resin for curing; a fourth process for releasing the upper die; a fifth process for cutting off a gate formed in the injection port portion; a sixth process for placing the light emitting element on the lead frame to be arranged on a bottom surface of the concave portion and electrically connecting the light emitting element and the lead frame; a seventh process for filling a second thermosetting resin in the concave portion; and an eighth process for heating up the second thermosetting resin for curing.
