PROBLEM TO BE SOLVED: To provide both a method for producing a sintered compact of glass ceramic which is capable of being baked with a wiring layer to be metallized with a low resistant conductive material such as Cu or Ag even with a smaller amount of glass than a conventional method and has high strength and a method for producing a wiring board. SOLUTION: This sintered compact of glass ceramic is obtained by molding mixed powder of 20-80vol.% of glass powder having 400 deg.C to 770 deg.C yield point and 1.5-8μm average particle diameter and 80-20vol.% of filler powder into a fixed shape and baking at 800-1,050 deg.C. This wiring board is obtained by molding mixed powder of 20-80vol.% of glass powder having 400 deg.C to 770 deg.C yield point and 1.5-8μm average particle diameter and 80-20vol.% of filler powder into a sheet shape, coating the surface of the sheetlike molded article with a metallizing paste and simultaneously baking the molding coated with the paste at 800-1,050 deg.C. Especially when the metallizing paste contains Cu, the simultaneous baking is carried out at 850-1,050 deg.C.
