Abstract
A ceramic bonded structure with a high bonding strength has a first member of a ceramic, a ceramic-modified bonding layer formed on at least a bonding surface of the first member by a thermal treatment, a metal layer formed on the ceramic-modified bonding layer, and a second member of a ceramic or metal bonded with the first member through the metal layer.

A ceramic bonded structure comprising a first member of a ceramic, a ceramic-modified bonding layer formed on at least a bonding surface of said first member, a metal layer formed on said ceramic-modified bonding layer, and a second member bonded to said first member through said metal layer.
A method of manufacturing a ceramic bonded structure, comprising the steps of:
- performing a first thermal treatment of a first member of a ceramic to modify a surface thereof and to form a ceramic-modified bonding layer thereon;
- performing the first thermal treatment of a second member of a ceramic to modify a surface thereof and to form a ceramic-modified bonding layer thereon;
- bringing said first and second members into contact with each other through a metal sheet interposed therebetween;
- and bonding said first and second members by performing a second thermal treatment at a temperature which allows a reaction between said metal sheet and said ceramic-modified bonding layers and is not higher than a melting point of said metal sheet.
A method of manufacturing a ceramic bonded structure, comprising the steps of:
- performing a first thermal treatment of a first member of a ceramic so as to modify a surface thereof and to form a ceramic-modified bonding layer thereon;
- bringing said ceramic-modified bonding layer into contact with a metal sheet;
- performing a second thermal treatment at a temperature at which said metal sheet and said ceramic-modified bonding layer react with each other and which is not higher than a melting point of a metal of said metal sheet so as to bond said ceramic-modified bonding layer and said metal sheet;
- and bonding a second member of a metal with said metal sheet.
