A transparent electro-conductive laminate comprising:
a substrate film made of a polyimide; and
a thin film made of an electro-conductive material and stacked on the substrate film, wherein
the polyimide is a polyimide
containing at least one repeating unit represented by the following general formula (1):
[in the formula (1), R1, R2, and R3 each independently represent one selected from the group consisting of a hydrogen atom, alkyl groups having 1 to 10 carbon atoms, and a fluorine atom, R4 represents an aryl group having 6 to 40 carbon atoms, and n represents an integer of 0 to 12],
having a glass transition temperature of 350°C to 450°C, and
having a linear expansion coefficient of 30 ppm/°C or less, the linear expansion coefficient being determined by measuring change in length under a nitrogen atmosphere and under a condition of a rate of temperature rise of 5°C/minute in a temperature range from 50°C to 200°C.
