PROBLEM TO BE SOLVED: To provide an electrochemical device which can be made thinner, and which is 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 package sheet has a proof strength of 390-980 N/mm, of which the hardness, especially Vickers hardness is 230-380 Hv. |
