IPC: H01G4/12
Filed: 1992-01-18
Abstract: PURPOSE:To prevent interlayer exfoliation from occurring when a carrier tape is removed from laminated green sheets which are temporarily adhered together. CONSTITUTION:Space patterns 3 having the same thickness as electrode patterns 2a and 2b are provided on at least one corner of ceramic green sheets 1a and 1b. Hence, the corner of this laminate is in an adhered state similarly to its center, and an even adhesion is assured both at the center and the corner of the laminate.

Also, the exfoliation of the green sheets 1a and 1b from each other at the center of the laminate where an adhesion is relatively low is prevented. Moreover, since the ceramic green sheets 1a and 1b are not adhesively laminated together at the corner of the laminate, the occurrence of deformation at a periphery of the laminate is prevented.
