PURPOSE: To provide a terminal connecting method by which precise positioning is carried out even if a row of terminals of a circuit board to be connected with a flexible substrate is long with an extremely narrow pitch and the terminals are highly precisely connected in a whole.
CONSTITUTION: The pitch of electrode terminals 21a of a long flexible substrate 21 is made narrower than the pitch of electrode terminals 1a of a circuit board 1 and after both electrode rows of the electrode terminals 1a and 21a are set to face each other and positioned temporarily, the terminal row of the electrode terminals 1a and the terminal row of the electrode terminals 21a are thermally press-bound while the row of the electrode terminals 21a are expanded mechanically until they match with the terminal row of the electrode terminals 1a. Consequently, even if the terminal row of the circuit substrate is long with an extremely narrow pitch, the electrode terminals are connected precisely with those of the long flexible substrate.
