Abstract:
A semiconductive film formed from a resin composition comprising poly(ether ether ketone) and a conductive filler, wherein the average value of its thickness is 30 to 250 μm, the maximum value of the thickness is 1 to 1.3 times as much as the minimum value thereof, the average value of its volume resistivity is 1.0×102 to 1.0×1014 Ωcm, the maximum value of the volume resistivity is 1 to 30 times as much as the minimum value thereof, and the number of reciprocating folds as determined in accordance with the testing method for folding endurance is at least 5,000 times, and a production process thereof.
