Stacked structure and method of manufacturing the same

A method of manufacturing a stacked structure, comprising the steps of:

• (a) forming a first electrode sheet with a first strip portion and a plurality of first plate portions extending in the form of comb teeth from a side edge of the first strip portion;
• (b) forming a second electrode sheet with a second strip portion and a plurality of second plate portions extending in the form of comb teeth from a side edge of the second strip portion;
• (c) forming a dielectric layer on surfaces of at least the first plate portions or the second plate portions, and on a surface of at least the first or second strip portion;
• (d) making the first and second electrode sheets overlap each other to determine the arrangement of the second electrode sheet with respect to the first electrode sheet such that the second plate portions overlap the first plate portions, and that regarding each of the first plate portions and one of the second plate portions to overlap this first plate portion, part of this first plate portion overlaps the second strip portion and part of this second plate portion overlaps the first strip portion, the step (d) being performed after the steps (a) to (c);
• and
• (e) folding the first and second strip portions together in a bellows shape or a spiral shape to stack the first plate portions and the second plate portions, the step (e) being performed after the step (d).

A stacked structure, comprising:

• a first electrode part with a first strip portion and a plurality of first plate portions extending from a side edge of the first strip portion;
• a second electrode part with a second strip portion and a plurality of second plate portions extending from a side edge of the second strip portion;
• and
• a dielectric layer,
• the first and second strip portions each having a bellows shape or a spiral shape, the first and second electrode parts being arranged such that the first plate portions and the second plate portions are stacked one by one alternately, the dielectric layer being placed between the first plate portions and adjacent ones of the second plate portions,
• the first strip portion having a plurality of first flat sections, each of the first plate portions extending from a corresponding one of the first flat sections, the first strip portion being not placed between any two of the first flat sections adjacent to each other,
• the second strip portion having a plurality of second flat sections, each of the second plate portions extending from a corresponding one of the second flat sections, the second strip portion being not placed between any two of the second flat sections adjacent to each other.

• (d) making the first and second electrode sheets overlap each other to determine the arrangement of the second electrode sheet with respect to the first electrode sheet such that the second plate portions overlap the first plate portions one by one, and that upper and lower positions of the first plate portions and the second plate portions with respect to each other are changed alternately in a longitudinal direction of the first or second strip portion, the step (d) being performed after the steps (a) to (c);
• and
• (e) folding the first and second strip portions together in a bellows shape to place each of the first plate portions and a corresponding one of the second plate portions one above the other in facing positions, this first plate portion and the corresponding second plate portion having been adjacent to each other in the longitudinal direction, the step (e) being performed after the step (d).

• (d) making the first and second electrode sheets overlap each other to determine the arrangement of the second electrode sheet with respect to the first electrode sheet such that none of the second plate portions overlaps one of the first plate portions closest to one edge of the first strip portion in a longitudinal direction of the first strip portion, and that the second plate portions overlap the other first plate portions one by one, the step (d) being performed after the steps (a) to (c);
• and
• (e) folding the first and second strip portions together in a spiral shape, so that the first plate portion with no second plate portion thereon is first placed on an adjacent one of the second plate portions, and then the first plate portions are successively placed on adjacent ones of the second plate portions, the step (e) being performed after the step (d).
