Flexible printed circuit board for catheter, catheter using same, and production method of catheter

摘要

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.
