A tape carrier package (TCP) with improved connecting terminals is disclosed. The TCP includes a base film of non-conductive material which carries a plurality of conductive leads on one surface thereof. A plurality of connecting terminals are deposited on the surface such as to be electrically interconnected to the ends of the conductive leads. Each of the connecting terminals has an acute-angled top portion and includes an inner member of a first material and an outer member of a second material plated on the inner member. The acute-angled top portion of the second material is easily deformable when the connecting terminal is pressed against a corresponding terminal provided on a board to be interconnected to the TCP. Thus, an adequate interconnection area is obtained between the TCP and the circuit provided on the board.
