Abstract:
A film-forming composition according to one embodiment includes a siloxane polymer (A) containing a condensation product (A1) and a condensation product (A2). In the (A), a contained amount of the (A1) is 75 percent or less by mass in terms of SiO2 with respect to the total of the (A1) and the (A2). The (A) has a weight-average molecular weight (MW) of 80 percent or greater of a molecular weight value M determined by expression (1) if RA1>RA2, expression (2) if RA1
