Kind Code:
A1
Abstract:
Provided is a colorless, transparent polyimide film, the polyimide film containing a polyimide and a volatile component, wherein as measured with a device for simultaneously measuring differential heat and thermogravimetric mass while raising the temperature from 120°C to 300°C in a nitrogen gas stream under the condition of a heating rate of 10°C/min and then maintaining the resultant film for 30 minutes at 300°C, the mass reduction from the total mass of the film before measurement corresponds to a volatile component content in the film, and a volatile component content ratio, which is the ratio of the volatile component content to the total mass of the film before the measurement, is 0.5-15 mass%.
