Abstract
In a method for manufacturing a ceramic multilayer substrate, when a green ceramic stack prepared by stacking a plurality of ceramic green sheets is fired simultaneously with a ceramic chip electronic component disposed inside the green ceramic stack and including an external terminal electrode to produce a ceramic multilayer substrate having the ceramic chip electronic component inside, a paste layer is disposed in advance between the ceramic chip electronic component and the green ceramic stack, and these three are fired.

A method for manufacturing a ceramic multilayer substrate by simultaneously firing a green ceramic stack prepared by stacking a plurality of green ceramic layers and a ceramic chip electronic component disposed inside the green ceramic stack and including a terminal electrode and an elementary body made of a ceramic sintered compact, the method comprising the steps of:
- preliminarily disposing a contact inhibitor between the ceramic chip electronic component and the green ceramic stack;
- and
- firing the green ceramic stack, the ceramic chip electronic component, and the contact inhibitor.
A ceramic multilayer substrate comprising:
- a ceramic stack including a plurality of stacked ceramic layers and a conductor pattern;
- and
- a ceramic chip electronic component disposed at an interface between any two adjacent layers of the plurality of stacked ceramic layers, including a terminal electrode and an elementary body made of a ceramic sintered compact, the elementary body having a gap at an interface between the elementary body and the ceramic stack.
A ceramic multilayer substrate comprising:
- a ceramic stack including a plurality of stacked ceramic layers stacked and a conductor pattern;
- and
- a ceramic chip electronic component disposed at an interface between any two adjacent layers of the plurality of stacked ceramic layers, including a terminal electrode and an elementary body made of a ceramic sintered compact, the elementary body including a green ceramic powder disposed at an interface between the elementary body and the ceramic stack.
