PROBLEM TO BE SOLVED: To solve the problems, such as the need for labor in mounting of auxiliary hook members 17, the expenses required for metallic tubes 19 and the short length of effective electroforming in a method of manufacturing various kinds of metallic tubes by using one or a plurality of wires 9 as a matrix and removing the wires 9 after performing the electroforming. SOLUTION: The method of fixing the wire 9 by using wire holding parts 22 having good electrical conductivity, then starting the electroforming by setting the wire to a holding tool 5, and in an initial period of this time, once immersing the wire down to the position of the wire holding parts 22 in a liquid surface 18 of an electroforming liquid and slightly electrolytically depositing material having electrical conductivity, such as nickel, on the wire 9, then performing the electroforming in the state of slight bringing up the holding tool 5 is adopted.
