The invention provides an electronic laparoscope with a front end LED illuminating function. The electronic laparoscope comprises a tube assembly, and the tube assembly comprises an illuminating assembly, a connecting sleeve, a lens, an image sensor assembly, a heat insulation pad, a rear end heat radiator and a steel tube. The illuminating assembly is located at the front end of the tube assembly, and the illuminating assembly is fixed to the connecting sleeve. The connecting sleeve is connected with the rear end heat radiator. The rear end heat radiator is fixed into the tube, and the illuminating assembly is located at the front end of the tube. The lens, the image sensor assembly and the heat insulation pad are located in the tube. The front end of the lens and the front end of the image sensor assembly are in butt joint with the illuminating assembly, and the rear end of the lens and the rear end of the image sensor assembly are in attached connection with the heat insulation pad.The electronic laparoscope has the advantages that the problem heat radiating of the front end is hard is solved, and therefore application of front LED illumination in the electronic laparoscope isachieved.
