Abstract:
1. A catheter comprising: a tube; an electronic component set in an anterior end or an intermediate part of the tube; a flexible printed circuit board inserted in the tube, the flexible printed circuit board comprising a metal support plate, a base insulating layer, and a signal line electrically connected to the electronic component, the signal line extending through the tube, from a vicinity of the electronic component to a posterior end of the tube, wherein the signal line is formed as a wiring pattern of the flexible printed circuit board, wherein a size of the metal support plate in a width direction is smaller than a size of a base insulating layer in the width direction, and therefore, both edge parts of the flexible printed circuit board in the width direction are free of the metal support plate, wherein the flexible printed circuit board is disposed in the tube, with both edge parts, which are free of the metal support plate, folded inside, and wherein the width of each of the edge parts that are free of the metal support plate is 20-1000 μm.
