Endoscope distal end with folded circuit board

摘要

An electronic endoscope having an internal circuit board bearing an electronic circuit arrayed thereon and coupled with a solid-state image pick-up element, with wires of the circuit board connected to lead wires passing through the insertion portion of the endoscope. The circuit board is folded along lines extending the axial direction of the distal end of the insertion portion, so as to divide the circuit board into a plurality of planar surfaces. The electronic circuit wiring portion and the lead wire connecting portion are laid out on the different planar surfaces.
