NITRIDE CERAMIC SUBSTRATE PRODUCTION METHOD AND NITRIDE CERAMIC BASE MATERIAL
First, a scribe line (110) is formed on a first surface (102) of a nitride ceramic base material (100) by a laser. Next, the nitride ceramic base material (100) is divided along the scribe line (110) . The scribe line (110) includes a plurality of recessed portions (112). The plurality of recessed portions (112) are formed in a row on the first surface (102) of the nitride ceramic base material (100). A depth (d) of each of the plurality of recessed portions (112) is equal to or greater than 0.70 times and equal to or smaller than 1.10 times an opening width (w) of each of the plurality of recessed portions (112). The opening width (w) of each of the plurality of recessed portions (112) is equal to or greater than 1.00 times and equal to or smaller than 1.10 times an inter-center distance (p) of the plurality of recessed portions (112).
