To check insulation of a pouch electric cell, probes are contacted to an electrode of a pouch electric cell and an aluminum layer of a pouch of the pouch electric cell, respectively, and then an electric characteristic value between the probes is measured. The probe contacted with the aluminum layer has a contact portion made of conductive elastic material. Also, insulation of the pouch electric cell is determined by comparing the measured electric characteristic value with a reference value. Thus, physical characteristics of an outer periphery of a flexible pouch may be sufficiently exhibited in measuring or checking insulation of a pouch electric cell such as insulation resistance, thereby improving reliability of electric contact and minimizing physical damage or deformation of the pouch electric cell. |
