PROBLEM TO BE SOLVED: To provide glass ceramics composed of SiO<SB>2</SB>-Al<SB>2</SB>O<SB>3</SB>-MgO-CaO based glass and Al<SB>2</SB>O<SB>3</SB>, and glass ceramics wiring board whose adhesion strength with a wiring conductor is high. SOLUTION: The glass ceramics wiring board is constituted by laminating a plurality of insulating layers which contains SiO<SB>2</SB>-Al<SB>2</SB>O<SB>3</SB>-MgO-CaO based glass and Al<SB>2</SB>O<SB>3.</SB>In the glass ceramics wiring board wherein the wiring conductors whose principal component is silver are formed on surfaces of the insulating layers and between the layers, the wiring conductor contains glass containing SrO. As a result, wettability of interface between the wiring conductor and the glass ceramics composed of SiO<SB>2</SB>-Al<SB>2</SB>O<SB>3</SB>-MgO-CaO based glass and Al<SB>2</SB>O<SB>3</SB>is improved, and adhesion strength of the wiring conductor is improved.
