PROBLEM TO BE SOLVED: To provide a paste applying method capable of uniformly applying a metallic paste on the surface of a ceramic sintered compact block having a non-through hole and an extremely small opening part and being treated in large quantities at a time. SOLUTION: In this method for applying the paste consisting essentially of a low resistance metal and an organic vehicle on the ceramic sintered compact block having the 5.0×5.0mm opening part 3 and at least one of the non- through hole of >=2 times of the opening part 3 in depth, the ceramic sintered compact block 1 is housed in a mesh-like vessel 4 having mesh size of >=0.5×0.5mm and the outside diameter or below of the block, dipped into the paste together with the mesh-like vessel 4, coated with the paste 5, transferred to a mesh-like vessel 4a with a lid, and excess paste is removed from the ceramic sintered compact block 1 by rotating the mesh like vessel 4a. At this time the ceramic sintered compact block 1 is housed so that the opening part 3 is inclined at 45 deg. to the vertical direction.
