A fabrication method of an industrial part having high-aspect-ratio through-hole sections using a punch and a die, includes: a first step of drilling a first hole section in a first sheet of sheet material with the punch; a second step of lifting the first sheet in tight contact with a stripper under a condition that the punch is not pulled out from the first hole section; a third step of lifting the punch so that a tip section of said punch is slightly drawn in from a bottom section of the lifted first sheet of sheet material; a fourth step of drilling a second hole section in a second sheet of sheet material with the punch; a fifth step of lifting the second sheet in tight contact with the first sheet under a condition that the punch is not pulled out from the second hole section; and a sixth step of lifting the punch so that a tip section of the punch is slightly drawn in from the bottom section of the lifted second sheet of sheet material. Subsequently, the fourth to sixth steps are repeated for lamination of a plurality of sheets of sheet material.
