Disclosed is a novel co-polyimide precursor for producing a polyimide having high transparency. The co-polyimide precursor comprises a unit structure represented by general Formula (A1) and a unit structure represented by general Formula (A2): wherein, in general Formula (A1), R1 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; and R2 and R3 each independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or an alkylsilyl group having 3 to 9 carbon atoms, wherein, in general Formula (A2), R4 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R5 and R6 each independently represent a hydrogen, an alkyl group having 1 to 6 carbon atoms, or an alkylsilyl group having 3 to 9 carbon atoms; and X represents a tetravalent group other than those represented by Formulae (A3):
