PROBLEM TO BE SOLVED: To provide a signal cable connection structure of an electronic endoscope in which a signal line and a soldered part have excellent durability by preventing strong tension from acting on individual thin signal lines. SOLUTION: In the signal cable connection structure of the electronic endoscope in which the tip parts of a plurality of shielded lines 11, 12, 13 and 14 inside a signal cable 7 inserted and arranged inside an insertion part 1 are connected to a circuit board 6 arranged adjacently on the rear side of a solid-state image pickup element 5 arranged inside the tip of the insertion part 1, two sets of shield twisted parts 1112 and 1314 for which the shields 11c and 12c/13c and 14c of at least two shielded lines 11 and 12/13 and 14 of the plurality of shielded lines 11, 12, 13 and 14 are twisted at the tip are formed, and the two sets of the shield twisted parts 1112 and 1314 formed in such a manner are distributed to both sides across the center line X in a width direction of the circuit board 6 and fixed to the circuit board 6.
