Abstract
A system for detecting a defective porous sheet includes a jig having a through-hole, a heating unit, a temperature sensor, a controlling unit, an air permeability-determining unit and a judging unit. In this manner, it is possible to provide a novel system for detecting a porous sheet, which may be a defective separator after being coated with a porous coating layer, beforehand by using the air permeability and shut-down temperature of the porous sheet itself.
