The present invention provides a flexible printed circuit board 100 having a band-like meander pattern as a whole, which includes multiple linear parts 1 configured in about parallel to each other and a folding margin connected to one end in the longitudinal direction of two adjacent linear parts of the multiple linear parts, and which can turn into a single linear product having a total length of not less than 300 mm when the folding margin 2 is double-folded at the about center thereof, and, at the folding margin 2, either of the two linear parts 1 connected to the folding margin 2 is folded back in the direction opposite by 180 degrees. As a result, a flexible printed circuit board for a catheter, which is sufficiently elongate for use as a signal line of a catheter, can be produced using a general-purpose production apparatus, which improves the degree of freedom of movement in a tube. |
