The invention provides a resin composition for optical use which comprises: (a) at least one member selected from the group consisting of: a polycarbodiimide represented by general formula (2): wherein R represents a diisocyanate residue, R<SUP>1 </SUP>represents a monoisocyanate residue, and n is an integer of 2 to 15; and a carbodiimide represented by general formula (3): <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>1</SUP>-N-C-N-R<SUP>1</SUP> (3) <?in-line-formulae description="In-line Formulae" end="tail"?> wherein R<SUP>1 </SUP>represents a monoisocyanate residue; and (b) a polycarbodiimide represented by general formula (1): wherein R represents a diisocyanate residue, R<SUP>1 </SUP>represents a monoisocyanate residue, and n is an integer of 20 to 200. Also disclosed are a resin sheet for obtained from the resin composition and an optical semiconductor device using the resin composition or the resin sheet.
