Provided are a chip-type electric double-layer capacitor and a chip-type electrolyte battery which can be formed not only in a disk shape but also in a square shape without leakage of electrolyte solution or intrusion of moisture from the outside. A cell is formed by laminating a positive electrode, a separator and a negative electrode, and connecting one end of a positive electrode terminal and one end of a negative electrode terminal to the positive electrode and the negative electrode, respectively. In the chip type electric double layer capacitor, the other ends of the terminals 20 and 22 extend to the outside through the wall 52 of the housing 50, the housing 50 is formed of an insulating material, and the positive terminal 20 and / or the negative terminal 22 are , A portion penetrating the wall 52 of the housing 50 has a roughened portion 26 subjected to a roughening process.
