Abstract:
1. A ceramic package having a bottom, an opening, and an opening circumferential edge formed by integral molding, wherein the ceramic package obtained by forming, on a plastic ceramic green sheet comprising (A) 100 parts by weight of a ceramic powder mainly composed of borosilicate glass, into which (B) 10 to 30 parts by weight of an acrylic copolymer obtained by polymerizing 100 parts by weight of at least one monomer selected from (meth)acrylic acid esters and 1 to 10 parts by weight of a monomer having a functional group of a hydroxyl group, acid amide group, or amino group and having a Tg in the range of more than −30° C. to not more than +10° C. is compounded, a conductor layer using a plastic conductive paste obtained by compounding, into 100 parts by weight of a conductive powder, 5 to 20 parts by weight of (C) a mixture of an acrylic copolymer obtained by polymerizing 100 parts by weight of at least one monomer selected from (meth)acrylic acid esters and 1 to 10 parts by weight of a monomer having a functional group of a hydroxyl group, acid amide group or amino group and having a Tg of not more than −30° C. and an ethylcellulose-based binder, press forming the resultant single layer of the ceramic green sheet having the conductor layer formed above to provide the bottom, opening and opening circumferential edge, and calcining the integrally press formed ceramic green sheet.
