<P>PROBLEM TO BE SOLVED: To prevent stored materials at an end of an insertion part of an endoscope from contacting each other without inhibiting diminishment of a diameter size of the endoscope. Ž<P>SOLUTION: An insertion part 10 of an electronic endoscope 2 includes an end 11 formed of a block 70. The block 70 is combined with a circuit board 43 mounted with a solid imaging element 41. An end of a light guide 34 is fixed to the block 70 through a cap 63 for pinching the circuit board 43. The light guide 34 is covered with a protective tube 62. The protective tube 62 is embedded with a net body 65 of braided metal wires. The protective tube 62 has a flat part 66 whose cross section is crushed to be oval at the end. The light guide 34 is fixed to the block 70 in order to accord the direction of the long axis X of the oval of the flat part 66 with the circumferential direction of the insertion part 10.
