PROBLEM TO BE SOLVED: To provide a new terminal-modified imide oligomer and varnish excellent in solubility in an organic solvent, solution storage stability and forming properties such as low melting viscosity and having high heat resistance and high mechanical properties such as tensile strength and elongation and a cured product thereof. SOLUTION: The soluble new terminal-modified imide oligomer is represented by general formula (1) [R is an aromatic diamine residue; m and n each satisfy the formulas m≥0, n≥0, 1≤m+n≤20 and 0≤m/(m+n)≤1 and sequence of recurring unit may be block-like or random-like].
