PROBLEM TO BE SOLVED: To provide an electrochemical capacitor capable of efficiently performing high output charge / discharge. A hybrid capacitor comprising a positive electrode 2 having a specific surface area of 100 m 2 / g or more, a negative electrode 3 made of a material capable of reversibly occluding and releasing lithium ions, and an electrolyte solution 5 made of an organic solvent containing lithium ions. 1, the negative electrode 3 is an amorphous carbon material in which vacancies have a three-dimensional regularity and are arranged in a macroscopic arrangement corresponding to a crystal structure. Preferably, the vacancies are Are formed from an amorphous carbon material which is formed in a spherical shape or a substantially spherical shape, is continuously arranged in an arrangement corresponding to a face-centered cubic, and the maximum length direction of the pores is in the range of 1 to 1000 nm. .
