摘要

PPROBLEM TO BE SOLVED: To provide a manufacturing method of a metallic sheet-like member having pores formed therein capable of inexpensively and efficiently manufacturing the metallic sheet-like member having the pores formed therein having the metallic sheet-like member of thin thickness in which the pores of small diameters are formed at a high numerical aperture. PSOLUTION: In the manufacturing method of the metallic sheet-like member having the pores formed therein, a large number of pores 16 are formed by etching at the high numerical aperture in a metallic sheet 24. The metallic sheet to be etched is supplied as a laminate 20 supported on a resin-made sheet 22. After the etching, the resin-made sheet of the laminate 20 is removed. PCOPYRIGHT: (C)2008,JPO&INPIT
