Patent ID: 8591801

Claim:
A process for manufacturing a conductor built-in ceramic, comprising: forming a conduction compact by using a conduction mixture which contains an electroconductive ceramic powder and a first binder; wherein forming an element compact comprises holding the conduction compact within a mold by pins for supporting a part of the conduction compact; filling the mold with a base mixture containing an insulating ceramic powder and a second binder through a filling port that is arranged at the mold to form an element compact comprising the conduction compact coated with the base mixture; and sintering the element compact, wherein Tg(A) represents the glass transition temperature of the first binder contained in the conduction mixture and Tg(B) represents the glass transition temperature of the second binder contained in the base mixture, and wherein a relationship Tg(B)<Tg(A) is satisfied; wherein Tv(A) represents the temperature at which the viscosity of the conduction mixture becomes 100 MPa·s and Tv(B) represents the temperature at which the viscosity of the base mixture becomes 100 MPa·s, and wherein a relationship Tv(B)<Tv(A) is satisfied.
