Abstract
A composition is provided which is useful for the production of a cured product which is excellent in heat resistance and light permeability. The composition includes a polysiloxane, at least one alkoxysilane partial condensate having no hydroxyl group selected from the group consisting of a T-type alkoxysilane partial condensate having no hydroxyl group and a Q-type alkoxysilane partial condensate having no hydroxyl group, and a phosphoric acid-based catalyst. The polysiloxane is represented by the following formula (1): In formula (1), m represents an integer of 5 to 3000 and R1 represents an alkyl group. The plurality of R1 may be the same or different.
