Abstract

ＬＥＤ等の発光素子の光度のばらつきを低減すると共に、複数の発光素子を密に並べることのできる発光部品を提供する。発光部品１Ａは、光を発する発光素子（ＬＥＤ２）の光度が所定範囲となるよう抵抗値調整された抵抗素子３が基板の裏面に形成され、抵抗素子３と、トランジスタ５を構成要素とする定電流回路が、ＬＥＤ２に定電流を供給し、ＬＥＤ２、トランジスタ５は、単位絶縁基板５の表面に形成され、単位絶縁基板５は、長方形であり、その対向する１対の辺の長さをｘ、１対の辺とは異なるもう一方の対向する１対の辺の長さをｙとした場合、ｘ／ｙの比の値が１～１．２５である。またこの発光部品１Ａは、抵抗素子３を２個有し、２個の抵抗素子３の双方に対し、抵抗値調整（トリミング）が施されている。
