摘要： A method of manufacturing an assembled conductor includes: arranging a plurality of peripheral wires having anisotropic cross-sectional shapes around a central wire; bundling the central wire and the peripheral wires that have been arranged, to form a conducting wire bundle; and rolling the conducting wire bundle to form the assembled conductor. The arranging includes a bending process for bending the plurality of peripheral wires in directions along imaginary lines that extend radially relative to an axis of the central wire on an imaginary plane intersecting the axis of the central wire.

摘要： A pin fin forming method is a method of forming a plurality of pin fins on a surface of a metal plate by subjecting the metal plate to extrusion using a die having a plurality of through-holes and a roll. The pin fin forming method includes placing the metal plate between the die and the roll, and pressing the metal plate from a first end of the metal plate to a second end of the metal plate, by moving the roll relative to the die. The metal plate is pressed from the first end of the metal plate to the second end of the metal plate, in a state where a side surface of the second end of the metal plate and an upper surface of the second end of the metal plate are fixed.

摘要： A surface roughening apparatus includes a first mold and a second mold. The first mold has a plurality of first protrusions. The first mold presses a metallic material to form recesses corresponding to respective shapes of the first protrusions in a surface of the metallic material. The second mold has a plurality of second protrusions. After the first mold presses the metallic material, the second mold presses the metallic material, thereby deforming each recess into an undercut shape. A height of each first protrusion is greater than a height of each second protrusion. A tip angle of each first protrusion is smaller than a tip angle of each second protrusion.
