An endoscope includes an operating section and an insertion section extending from the operating section. The insertion section has a flexible tube formed of a flexible synthetic resin and having a plurality of insertion channels extending in the axial direction of the flexible tube. A rigid member is attached to the distal end of the tube. The rigid member has through holes communicating with the channels, respectively. An objective optical system is arranged in one of the through holes. An image guide fiber is passed through one of the insertion channels, and its distal end portion is inserted fixedly in the through hole and optically connected to the objective optical system.
