ELECTRICAL DOUBLE LAYER CAPACITOR WITH EXCELLENT HEAT RESISTNACE AND SUPPORTING STABILITY

Disclosed is an electric double layer capacitor with high heat resistance and high supporting stability which has an inner structure which is robust against a vibration or an impact by inserting a supporter which supports a winding device into a case and is used as a measurement while drilling (MWD) power source by using an electrolyte and a separation layer for a high temperature. The electric double layer capacitor with the high heat resistance and the high supporting stability according to the present invention includes a case which is combined with a bottom cover and receives the electrolyte inside, the winding device which is inserted into the case and in which a first electrode, the separation layer, and the second electrode are successively stacked and wound, the supporter which is mounted on the upper side of the winding device, supports the winding device, and includes a hollow part, a top insulation plate which is mounted on the supporter, a header which is combined with the outer circumference of the supporter and covers the upper side of the case, a header pin which is combined to pass through the header and the top insulation plate, a first lead wire which is withdrawn from the first electrode of the winding device and protrudes to the outer wall of the top side of one side of the case, and a second lead wire which is withdrawn from the second electrode of the winding device, passes through the hollow part of the supporter, and protrudes to the outside of the header and the top insulation plate.
