Abstract:
1. A film-forming composition comprising: a siloxane polymer (A) containing a condensation product (A1) made from a starting material, which is an alkoxysilane containing a tetra-functional alkoxysilane represented by the following formula (1), and a condensation product (A2) made from a starting material, which is an alkoxysilane represented by the following formula (2); and an organic solvent (B), wherein, in the siloxane polymer (A), a contained amount of the condensation product (A1) is 75 percent or less by mass in terms of SiO when the weight-average molecular weight and the SiO wherein formula (1) is Si(OR wherein formula (2) is R wherein expression (1) is M=(R wherein expression (2) is M=(R wherein expression (3) is M=M
