Electrochemical cell

An electronic component comprising:

• a recessed container including a recessed portion, the recessed portion having a step portion between a bottom surface and an upper end portion,
• wherein the recessed container comprises a plurality of laminated sheets defining an inner surface of the recessed portion and
• wherein the step portion includes a first step portion and a second step portion and an upper surface of the first step portion and an upper surface of the second step portion are on the same plane;
• a first conductor that extends outside of the recessed container from an upper surface of the step portion by way of through-holes in the recessed container;
• a second conductor that extends outside of the recessed container from the upper surface of the step portion by way of through-holes in the recessed container,
• wherein the first conductor resides on the first step portion, and the second conductor resides on the second step portion;
• a bottom laminated sheet of the plurality of laminated sheets having a first wiring layer thereon connected to laterally displaced through-holes of the first conductor and a second wiring layer thereon connected to laterally displaced the through-holes of the second conductor;
• a first electrode connected to the first conductor on the upper surface of the step portion by a first collector;
• a second electrode connected to the second conductor on the upper surface of the step portion by a second collector;
• an electrolyte in contact with the first electrode and the second electrode;
• and
• a sealing plate bonded to the upper end portion of the recessed portion by a sealing material and sealing the recessed portion.
