PURPOSE: To connect the connector patterns of filmy connecting members to the connecting terminals of the entitled printed circuit board without fail while avoiding short circuit even if the positions of the filmy connecting members are slightly out of place by a method wherein the dummy terminals not electrically connected to other conductor patterns are formed at regular intervals between the connecting terminals.

CONSTITUTION: Multiple connecting terminals 2 0.5mm wide connected to the conductor circuit of filmy connecting members are formed at specific intervals on the entitled printed circuit board 1. Dummy terminals 3 0.1mm wide not electrically connected to other conductor patterns are formed at regular intervals of 0.1mm between adjacent connecting terminals 2. In order to connect this printed circuit board 1 to other device using a heat sealed connector 20, the heat sealed connector 20 is to be arranged in the state wherein conductive layers 22 correspond to the connecting terminals 2 so as to be fixed by heating press under a specific pressure and at a specific temperature.
