An assembly method for first and second articles is disclosed. A first substrate with a plurality of first articles and a second substrate with a plurality of second articles are selected. The articles on the flexible substrate webs with different pitches are assembled together by displacing portions between the first articles of one web out of plane to move the first articles on that web to the same shorter pitch as the second articles on the other web, aligning the two webs to register corresponding first and second articles on the two webs, and assembling the corresponding articles together. The assembly may be used for example in the making of RFID tags, labels and inlays.

A film-covered battery houses, in a film covering material 4 obtained by stacking a heat sealing layer 13, a barrier layer 12, and a protective layer 11, a battery element 6 obtained by arranging positive and negative electrodes through separators and has a sealing portion that seals a periphery of the film covering material 4 housing the battery element 6.
