1. An ultrasonic endoscope comprising:
an ultrasound transducer in a distal end part having a longitudinal axis;
a distal end body block component in which the ultrasound transducer, an observation optical system, and an illumination optical system are mounted;
a channel block component which is formed separately from the distal end body block component and in which a channel into which a treatment tool is inserted is mounted; and
a flexible printed circuit part that is disposed inside the distal end body block component and is connected to the ultrasound transducer,
wherein the flexible printed circuit part includes a transducer connection portion that is positioned on one side to be an ultrasound transducer side, an offset wiring portion that is positioned on the other side to be an opposite side to the one side, is disposed in an offset manner at a position away from the longitudinal axis toward an outside in a radial direction of the longitudinal axis with respect to the transducer connection portion and in a width direction of the flexible printed circuit part, and is formed along the channel block component, and an intermediate connection portion that connects the transducer connection portion and the offset wiring portion,
the offset wiring portion has a cable bonding portion to which loose cables are bonded, on an opposite side to the intermediate connection portion,
the cable bonding portion is covered with an insulating member, and
the insulating member is positioned inside the distal end body block component.
