Abstract
Provided is a method for manufacturing a metal structure in which an array of a plurality of pin arrangements is formed on a surface of a metal, in which the method includes: performing a laser processing along a route between pin regions in which the pins are to be formed on a metal base material to form a dross on the pin regions, and repeating the laser processing. As the dross formed in each pin region is repeatedly cast and recast during the repetitive laser processing, the recast layer is formed in a shape of the pin.

A method for manufacturing a metal structure in which an array of a plurality of pin arrangements is formed on a surface of a metal, the method comprising:
- performing a laser processing along a route between pin regions in which the pins are to be formed on a metal base material to form a dross on the pin regions;
- and
- repeating the laser processing,
- wherein as the dross formed in each of the pin regions is repeatedly cast and recast during the repetitive laser processing, the recast layer is formed in a shape of the pin.
A metallic fine structure characterized in that, in a metal structure in which an array of a plurality of pin arrangements is formed on a surface of a metal, a laser processing is performed along a route between pin regions in which the pins are to be formed on a metal base material to form a dross on each of the pin regions, and as the dross formed on each pin region is repeatedly cast and recast by repeatedly performing the laser processing, the recast layer is formed in a shape of the pin.
