摘要

PPROBLEM TO BE SOLVED: To provide a roll for drilling to continuously and efficiently drill fine holes the maximum length of width of which is more than 0 mm and less than 3 mm on a metallic foil or a metallic sheet, a manufacturing device and a manufacturing method of a multiple fine hole metallic material using it and the multiple fine hole metallic material manufactured by them. PSOLUTION: This roll 1 for drilling is constituted of a pair of a metallic roll 2 having a projection 3 and a receiver roll 4 to receive pressing force generated by this projection 3 of the metallic roll 2 and finally manufactures the multiple fine hole metallic material 9 by drilling ruptured holes 6 by inserting and interposing a drilling metallic material 5 between them, height of the projection 3 provided on a surface of this roll 1 for drilling is made more than 120 % of thickness of the drilling metallic material, a rising angle from a surface of the metallic roll 2 is made 90 to 135 and the maximum length of width of a head end of the projection 3 is made more than 0 mm and less than 3 mm.
