A direction input device is provided to increase the productivity and to improve the reliability of an operation of the direction input device by manufacturing the piezoelectric sensor through a molding process. An input unit(10) is formed as to tilt from a horizontal position to all directions. A plurality of first piezoelectric sensors(31) are installed at the lower part of the input unit and corresponds to a first outward directions. The first piezoelectric sensor generates a sensing signal which is in proportion to a tilting pressure of the input unit. A plurality of second piezoelectric sensors(32) are installed around the outer edge of the first piezoelectric sensors and correspond to a plurality of second outward directions. The second piezoelectric sensor generates a second sensing signal which is in proportion to a pressing pressure. A plurality of pressing units(40) are installed on the top of each second piezoelectric sensor. In case the first or the second sensing signal is over a set value, a control unit extracts and inputs the data allocated to the outward direction corresponding to the piezoelectric sensor from a memory unit.
