PROBLEM TO BE SOLVED: To provide the failure detecting method of a stacked ceramic capacitor wherein a defective insulation layer can be specified accurately. SOLUTION: In a stacked ceramic capacitor set as the application object of the failure detection method, a plurality of internal electrodes 36, 37 are embedded in layers in the inside of a dielectrics substrate 31. The internal electrodes 36, 37 are constituted, by electrically conducting to a pair of terminal electrodes 32, 33 which are applied to the external surface of the dielectrics substrate 31. When a failure is detected, the stacked ceramic capacitor is set under a temperature environment of at least 60°C and so ground that the ground surface perpendicular to the direction of lamination of the internal electrodes 36, 37 is produced, and the insulation resistance between the terminal electrodes 32-33 is measured. Poor insulation is detected by increase of measuring resistance value. COPYRIGHT: (C)2005,JPO&NCIPI
