Endoscope

The purpose of the present invention is to nip in the bud an undesirable situation caused by bending of a connection section between an active bending section and a passive bending section. In an endoscope provided with a connection cylinder (50) in which a bendable active bending section and a passive bending section are disposed in this order from the tip and which connects the active bending section and the passive bending section, the active bending section and the passive bending section each comprise a plurality of joint cylinders (30, 40). A coil member (60) into which an operation wire (90) for bending the active bending section is inserted is fixed to the connection cylinder (50), and a notch (43) for increasing the rotational degree of freedom of a joint cylinder (40A) of the passive bending section that is connected to the connection cylinder (50) and rotates is formed in the vicinity of the coil member (60). 将因主动弯曲部和被动弯曲部之间的连接部的弯曲而产生的不良情况防患于未然。在具备从前端依次配置有可弯曲的主动弯曲部及被动弯曲部并连接所述主动弯曲部及所述被动弯曲部的连接圆筒(50)的
