The evaluation method of a separator for a nonaqueous electrolyte battery according to the present invention includes: placing opposite an upper jigserving also as a conductive electrode and a lower jigserving also as a conductive electrode in both sides of the separator sample; and measuring the relationship between an applied voltage and a passed current between the upper jigand the lower jigwhile applying a pressure to between the upper jigand the lower jigto evaluate the separator. At this time, by fitting a foreign materialin any shape between the separator sampleand one of the upper jigand the lower jig, an evaluation of the separator simulating the presence of a foreign material affecting adversely the separator can be performed.
