PROBLEM TO BE SOLVED: To provide a polyimide precursor and a polyimide having excellent properties such as translucency, bending resistance, and high heat resistance and also having a very low thermal linear expansion coefficient and solvent resistance.SOLUTION: A polyimide precursor is a semialicyclic polyimide precursor obtained from: a tetracarboxylic acid component with a chemical structure having at least one aliphatic six-membered ring and no aromatic ring, and two diamine components with a chemical structure having at least one ester bond and an aromatic ring. |
