Abstract
A biaxially oriented thermoplastic resin film has at least one surface of which has protrusions each having a height of 1 nm or more and less than 2 nm at a density of 1×10to 1×10protrusions per mm. The thermoplastic resin film is capable of suppressing generation of coarse protrusions and contaminants, and defects in a processing process while having slipperiness.
