摘要：
A molecular weight of a polymer is measured by a process including steps of: heating a polymer portion with a heating device, measuring, with a temperature measuring device, the difference between temperatures of at least two points of the polymer portion at each of which the polymer portion is subjected to a thermally different influence from each other by the heating device, and estimating the molecular weight of the polymer which corresponds to the difference between the temperatures obtained by the measuring step according to a relationship between the temperature difference and the molecular weight of the polymer which relationship has been beforehand obtained.
