PURPOSE:To print clearly and enable forming a print which does not disappear, by placing different color inks into incised parts formed by laser marking. CONSTITUTION:A predetermined mark is incised in the surface of an electronic part by laser marking, then an ink 2 is applied to the surface, and the surplus of ink 2 adhered to the parts other than the incised parts 1 is removed by blasting or brushing. In this case, it is particularly effective that the particle diameter of an abrasive power used in blasting or the diameter of a brush used in brushing is set to be larger than the width of the laser incision. Accordingly, clear print which does not disappear can be obtained, and manufacturing cost can be reduced. |
