The imaging catheter (100) comprises a metal wire tube (110), an end head (130) and a fixing ring (140). A metal wire exposed at one end of the metal wire tube (110) forms a conductive end (112), and the conductive end (112) is electrically connected to the end head (130) so that static electricity at the end head (130) can be led out by using the metal wire as a conductive medium, thereby reducing the influence of static electricity on an image capture assembly (200) at the end head (130) as well as the harm of static electricity to the human body. Meanwhile, since there is no need to additionally provide a ground lead at the image capture assembly (200), space is effectively saved. The fixing ring (140) wraps the conductive end (112) and is connected to the end head (130) so that the metal wire tube (110) is connected and fixed to the end head (130). In addition, since the conductive end (112) is an exposed metal wire, a pointed part formed by the metal wire may be effectively prevented from injuring the human body by means of the fixing ring (140) wrapping the conductive end (112), and the usage effect is thus better.
