The invention claimed is: 1. A glass ceramic material comprising: a glass containing SiO 2 , B 2 O 3 , Al 2 O 3 , and M 2 O, wherein M is an alkali metal; and a filler containing quartz, Al 2 O 3 , and ZrO 2 , the glass ceramic material containing the glass in an amount of 57.4% by weight or more and 67.4% by weight or less, the quartz in the filler in an amount of 29% by weight or more and 39% by weight or less, the Al 2 O 3 in the filler in an amount of 1.8% by weight or more and 5% by weight or less, and the ZrO 2 in the filler in an amount of 0.3% by weight or more and 1.8% by weight or less. 2. The glass ceramic material according to claim 1 , wherein the glass contains the SiO 2 in an amount of 72% by weight or more and 88% by weight or less, the B 2 O 3 in an amount of 10% by weight or more and 26% by weight or less, the Al 2 O 3 in an amount of 0.1% by weight or more and 2% by weight or less, and the M 2 O in an amount of 1% by weight or more and 3% by weight or less. 3. The glass ceramic material according to claim 1 , wherein the glass ceramic material is free from cristobalite crystals. 4. A laminate comprising multiple glass ceramic layers each of which is a sintered article of the glass ceramic material according to claim 1 . 5. An electronic component comprising: a multilayer ceramic substrate including the laminate according to claim 4 ; and a chip component mounted on the multilayer ceramic substrate. 6. The glass ceramic material according to claim 2 , wherein the glass ceramic material is free from cristobalite crystals. 7. A laminate comprising multiple glass ceramic layers each of which is a sintered article of the glass ceramic material according to claim 2 . 8. A laminate comprising multiple glass ceramic layers each of which is a sintered article of the glass ceramic material according to claim 3 .
