PROBLEM TO BE SOLVED: To provide an electric double layer capacitor having high performance with a low rate of self-discharging. SOLUTION: The electric double layer capacitor includes a capacitor body having a positive electrode 1a, a negative electrode 1b and a separator interposed between the positive electrode 1a and the negative electrode 1b, and a container for sealing the capacitor body together with an electrolyte. In the electric double layer capacitor, each of the positive electrode 1a and the negative electrode 1b has a metal layer for forming a collector electrode, a polarizable electrode for forming the kneaded material layer 3 of an active carbon main body on the surface of the collector electrode, and a pressure machining part 4 for correcting a shearing deformation at the peripheral edge of the laminated region of the metal layer and the kneaded material layer 3.
