PROBLEM TO BE SOLVED: To provide a resin having a low permittivity and heat resistance. SOLUTION: Provided is a polyamic acid composition comprising repeating units represented by formula (1) [wherein R1 and R2 are each any one group selected from methylene, oxygen, C(CH3)2, C(CF3)2, and COO; R3 is any one group selected from hydrogen, a 1-10C hydrocarbon group, (meth) acryloyloxyethyl, (meth)acryloyloxy-n-propyl, (meth)acryloyloxy-i-propyl, and (meth)acryloyloxy-n-butyl; R4 is hydrogen, a 1-4C hydrocarbon group, a 1-4C alkoxyl, an ester group, carboxyl, or hydroxyl; R5 is hydrogen, a 1-6C hydrocarbon group, R6-CO, or R6COO (wherein R6 is a 1-4C hydrocarbon group); (p) and (q) are each an integer of 0-2; and (r) and (s) are each o or 1].
