PROBLEM TO BE SOLVED: To provide a helical antenna formed to a built-in type so as not to deteriorate the characteristic of the antenna though the antenna has high precision, its excellent characteristic and ease of incorporation to a communication equipment and miniaturization and to provide its manufacturing facility and its manufacturing method. SOLUTION: A controller controls a core drive section 20 and a roller drive section 50 at a rotational speed that is preset by a diameter of a core and a roller in use, and controls the core drive section 20 at a mobile speed set by an operating frequency hand of an antenna to move the in a horizontal direction while driving the core and the roller respectively. The core and the roller are driven in an opposite direction while being in contact with each other, and paste contained in a pass box 31 is moved along the surface of the roller as the roller is driven and printed on the surface of the core. In this case, since the core is moved in the horizontal direction while being rotated, a helical line 11 is formed on the core. |
