PROBLEM TO BE SOLVED: To provide a glazed substrate having a glazed layer formed in the form of a convex on a ceramic substrate in which the winding or waving of the apex of the convex glazed layer is reduced. SOLUTION: The glazed substrate 20 is composed of the ceramic substrate 2, a first glazed layer 4 formed on the main side of the ceramic substrate 2 and having a pair of linear channels 8 opening oppositely to each other on the top face, a second glazed layer 6 shaped into a long and slender convex formed across the pair of channels 8, and has the second glazed layer 6 formed linearly along the upper edge portions of the channels 8. Consequently, the glazed substrate 20 can be made one restraining the winding or waving of the apex of the second glazed layer 6. COPYRIGHT: (C)2006,JPO&NCIPI
