Abstract
In an electronic component including: a sintered body with an internal electrode embedded; and an external electrode formed on the outer surface of this sintered body that is connected to the above internal electrode, a porous external electrode having numbers of pores is formed in the sintered body and thereafter the resin is impregnated through the pores. Thereby the pores of the external electrode are impregnated with a substance of the same sort as that of the buffer material as well as the buffer material interposes between the sintered body and the internal electrode.
Claims15
An electronic component, comprising:
- a sintered body with an internal electrode embedded;
- and
- an external electrode formed on an outer surface of the sintered body and connected to said internal electrode,
- wherein a buffer material is interposed between said sintered body and said internal electrode, and said external electrode comprises a porous conductive member having numbers of pores, and said pores of the external electrode are impregnated with a substance of a same sort as that of said buffer material.
A method for manufacturing an electronic component, including:
- a sintered body with an internal electrode embedded;
- and
- an external electrode formed on an outer surface of the sintered body connected to said internal electrode,
- comprising:
- a step of stacking a plurality of insulator sheets printed with a conductive paste in use for the internal electrode to fabricate a multilayer body;
- a step of burning said multilayer body to fabricate a sintered body having voids between the sintered body and the internal electrode;
- a step of forming the external electrode comprising a porous conductive member on the surface of said sintered body so as to be electrically continuous and connected to the internal electrode;
- a step of impregnating a resin through pores of said external electrode into the said voids and into the pores of the external electrode;
- and
- a step of hardening said impregnated resin.
