    • This invention provides a separator for electrical or electronic parts which is characterized in that the increase ratio in internal resistance of the separator before and after its heat treatment at 300° C. for 45 minutes is within 25%, where the internal resistance is calculated according to the following equation (1): (internal resistance)={(electrical conductivity of electrolytic solution/(electrical conductivity of electrolytic solution-injected separator)}×(thickness of separator)  equation (1)wherein (electrical conductivity when the electrolytic solution is injected into separator) is the electrical conductivity calculated from the AC impedance measured by sandwiching the electrolytic solution-injected separator between two electrodes.
    • 本发明提供一种用于电气或电子部件的隔膜,其特征在于,隔板在300℃下热处理45分钟之前和之后的内阻增加率在25%以内,其中内阻根据 (1):<?in-line-formula description =“In-line formula”end =“lead”?>(internal resistance)= {(电解液的导电性/(电解液 - 注入分离器)}×(分离器的厚度)方程式(1)<?in-line-formula description =“In-line Formulas”end =“tail”?>其中(电解液注入分离器时的导电率) 通过将电解液注入的分离器夹在两个电极之间测量的由AC阻抗计算的电导率。
