Zusammenfassung:	PURPOSE: To efficiently and surely inspect pinhole inferiority of a food air-tight vessel made of a food package sheet of laminating structure including a conductive layer made of a metal foil. CONSTITUTION: In a pinhole inferiority inspection method of a food air-tight vessel A formed by melting a food package sheet S laminating resin layers Sb, Sc sandwiching a conductive layer Sa, a ground electrode 21 is brought into contact with the conductive layer Sa of the sheet A, voltage is applied between the ground electrode 21 and a detection electrode 23 brought into contact with or neared to the surface of the food air-tight vessel A, and presence of charge current is detected.
