Abstract

Provided is an electric double-layer capacitor and the like, which may be easily manufactured. In a recessed container ( 2 ) constituting a package of an electric double-layer capacitor ( 1 ), a step portion ( 4 ) is formed. With this, the recessed container ( 2 ) has two parallel bottom surfaces which are not provided in the same plane, that is, a first bottom surface constituting a bottom portion of a recessed portion ( 13 ) and a second bottom surface constituting an upper surface of the step portion ( 4 ). The first bottom surface and the second bottom surface respectively have metallic layers ( 11, 9 ) formed thereon, which pass through the recessed container ( 2 ) toward an outside to respectively connect to terminals ( 12, 10 ). Electrodes ( 6, 5 ) are respectively connected to the upper surfaces of the metallic layers ( 11, 9 ).

Claims (14)

1. An electronic component, comprising:

a container including a hollow portion in which a first bottom surface and a second bottom surface, which is provided in a plane different from the first bottom surface, are formed;

a first conductor, which is formed on the first bottom surface and passes through the container toward an outside;

a second conductor, which is formed on the second bottom surface and passes through the container toward the outside;

a first electrode disposed on the first conductor in the hollow portion; a second electrode, which is disposed on the second conductor in the hollow portion and is opposed to the first electrode at a predetermined interval; and

an electrolyte, which is provided in contact with the first electrode and the second electrode.

2. An electronic component according to claim 1 , wherein: the hollow portion comprises a step portion including a step, which is formed at a bottom surface of the hollow portion; and the second bottom surface comprises an upper surface of the step portion.

3. An electronic component according to claim 1 , wherein the first conductor and the second conductor are connected to a first connection terminal and a second connection terminal, respectively, which are formed on a rear surface of the container.

4. An electronic component according to claim 1 , further comprising a third conductor, which is disposed on a surface of the second electrode on a rear side of a surface opposed to the first electrode, and is connected to the second conductor.

5. An electronic component according to claim 1 , wherein: the first electrode and the second electrode are a negative electrode and a positive electrode, respectively; and the second electrode has a surface area larger than a surface area of the first electrode.

6. An electronic component according to claim 1 , further comprising a protruding portion, which is formed at a side of an end portion of a step portion and protrudes in an upper direction of the container.

7. An electronic component according to claim 1 , wherein each of the first conductor and the second conductor passes through a side surface of the hollow portion.

8. An electronic component according to claim 1 , wherein the first conductor passes through the first bottom surface, and the second conductor passes through the second bottom surface.

9. An electronic device, comprising: the electronic component according to claim 1 ; charging means for charging the electronic component; another electronic component exerting a predetermined function; and power supply means for supplying power to the another electronic component with use of electric charge that is stored by the charging means.
