摘要:
A luminescent device including a die pad lead composed of an inner lead and an outer lead, a case for uniting the inner lead, a light emitting diode chip mounted on a first predetermined position of one main surface of the inner lead, and a transparent sealing material portion for sealing the light emitting diode chip and a part of the one main surface. The case seals the inner lead other than an area sealed by the transparent sealing material portion, and the inner lead of the die pad lead has bending portions at least two places including a first bending portion and a second bending portion. A rear of the first predetermined position in the inner lead of the die pad lead is exposed outside the case, and the second bending portion is formed in the case so that the outer lead extends from a side of the case.
