The invention relates to a super capacitor assembled by manganese series oxide electrodes with meshed nano-structures, which is large in specific capacity and low in cost. The super capacitor assembled by the manganese series oxide electrodes with the meshed nano-structures is characterized by comprising at least one manganese series oxide electrode with a unique meshed nano-structure, a membranesoaking in an electrolyte solution is clamped between the manganese series oxide electrode with the unique meshed nano-structure and a congeneric electrode or other electrodes such as an active carbon electrode and the like, a shell is coated outside and a negative wire and a positive wire are led out, thus the super capacitor is assembled. The super capacitor assembled by the manganese series oxide electrodes with the meshed nano-structures adopts composite oxides of transition metal manganese, which are abundant in material, as electrode material instead of precious metal, so that the supercapacitor is low in cost.
