PROBLEM TO BE SOLVED: To provide a method efficiently manufacturing an electrochemical device preventing shrinkage exceeding a fixed value even at temperature causing heat shrinkage, preventing short circuit between positive and negative sheets, not having bad effect on the ionic conductivity of a separator, having high safety causing no hard short-circuit and having high capacity, and to provide manufacturing equipment for the electrochemical device and to provide the electrochemical device. SOLUTION: In the manufacture of the electrochemical device having a stacked body formed by stacking a positive electrode and a negative electrode through the separator, at least the positive electrode and/or the negative electrode are/is interposed between the separators, and when parts of the periphery parts of the separators are melt-bonded to form the bag-shaped separator, the width of the bonded part in the periphery part of the separator is specified to 0.3 mm or less.
