PURPOSE: To easily obtain crystallized glass material having light-transmissive parts with spherical patterned part, etc., on a surface and inside part thereof.

CONSTITUTION: This crystallized glass material 1 forms patterns by the presence of crystallized spherical parts 4 and circular parts 5 in a light transmissive part 3 integrally fused with base 2 formed by crystallized glass. This glass material is produced by melting the crystallized glass and arranging a transparent body formed by a metallic mold at a forming mold and adding powdery and granular material such as crystallized glass, then executing heat treatment to it.
