PROBLEM TO BE SOLVED: To provide an electrochemical device which can be made thinner, and which is low in capacitance and superior in resistance to bending.SOLUTION: An electrochemical device comprises: a device main body 10 arranged by laminating a pair of a first internal electrode and a second internal electrode together with a separator layer sandwiched therebetween; a package sheet 4 covering the device main body; a first lead terminal 18 led to outside the package sheet 4; and a second lead terminal 28 led to outside the package sheet 4. The first lead terminal 18 and the second lead terminal 28 are led from position opposite to each other to outside seal parts 40 and 42. In a position corresponding to the seal parts 40 and 42, the first lead terminal 18 and the second lead terminal 28 have thinner regions 60. In the regions 60, the first lead terminal 18 and the second lead terminal 28 are smaller in thickness than lead end portions thereof. At least a part of each thinner region 60 protrudes from peripheral edges 4d1 and 4d2 of the package sheet 4 outwardly; and the parts of the thinner regions 60 so protruding outwardly are also covered by the respective seal parts 40 and 42. |
