Abstract
A method for manufacturing a ceramic sintered body substrate includes of disposing a first metal paste on a surface of a ceramic substrate, and of firing the ceramic substrate on which the first metal paste is disposed. In the disposing the first metal paste, the first metal paste contains a plurality of first metal powders, a plurality of active metal powders, and a plurality of inorganic fillers excluding metals, and in the firing the ceramic substrate, a firing temperature is equal to or higher than a melting point of the first metal powders.

A method for manufacturing a ceramic sintered body substrate, comprising:
- disposing a first metal paste on a surface of a ceramic substrate;
- and
- firing the ceramic substrate on which the first metal paste is disposed, wherein
- in the disposing the first metal paste, the first metal paste contains a plurality of first metal powders, a plurality of active metal powders, and a plurality of inorganic fillers excluding metals, and
- in the firing the ceramic substrate, a firing temperature is equal to or higher than a melting point of the first metal powder.
A ceramic sintered body substrate comprising:
- a ceramic substrate;
- and
- a first metal member disposed on a surface of the ceramic substrate, wherein
- the first metal member contains a plurality of inorganic fillers, a first metal, and a metal compound, and
- the metal compound is disposed on at least a part of surfaces of the plurality of inorganic fillers and at least a part of a surface of the ceramic substrate.
A light-emitting device comprising:
- a ceramic sintered body substrate including a ceramic substrate and a first metal member disposed on a surface of the ceramic substrate, the first metal member containing a plurality of inorganic fillers, a first metal, and a metal compound, the metal compound being disposed on at least a part of surfaces of the plurality of inorganic fillers and at least a part of a surface of the ceramic substrate;
- and
- a light-emitting element electrically connected to the first metal member of the ceramic sintered body substrate.
A light-emitting device comprising:
- a ceramic sintered body substrate including a ceramic substrate and a first metal member and a second metal member disposed on a surface of the ceramic substrate, the first metal member containing a plurality of inorganic fillers, a first metal, and a metal compound, the metal compound being disposed on at least a part of surfaces of the plurality of inorganic fillers and at least a part of a surface of the ceramic substrate;
- and
- a light-emitting element electrically connected to the first metal member or the second metal member of the ceramic sintered body substrate.
