Adhesive tape for temporary-attachment of green sheets for ceramic electronic devices and method for producing ceramic electronic devices

A method for producing a ceramic electronic device, comprising the steps of:

• allowing a green sheet laminate of ceramics to adhere to a base via an adhesive tape, and thereafter cutting the laminate into chips;
• and peeling the chips off a surface of the base while cooling the adhesive tape,
• wherein the adhesive tape comprises a substrate film and an adhesive layer provided on at least one face of the substrate film, the adhesive layer comprising an adhesive composition, the adhesive composition containing a side-chain crystallizable polymer, wherein the side-chain crystallizable polymer comprises as a component an acrylic acid ester and/or a methacrylic acid ester which has a straight-chain alkyl group including 16 or more carbon atoms as a side chain, the side-chain crystallizable polymer having a first-order melting transition occurring in a temperature range narrower than about 35° C.,
• wherein the adhesive layer has a modulus of elasticity of about 5×104 Pa to about 1×108 Pa, so that the lateral deformation stress, which is applied owing to the thickness of a cutting blade as it is inserted, can be reduced by the elastic properties of the adhesive layer.
