A pointing device is provided. The pointing device is configured to output a movement instruction signal for moving a cursor on a display in an instructed direction and includes: a pointing stick; a cursor movement including a +X sensor, −X sensor, +Y sensor and −Y sensor configured to sense a cursor movement instruction signal for instructing the cursor to move in +X direction, −X direction, +Y direction and −Y direction, respectively, according to an operation to the pointing stick; and a stick Z direction operation detector configured to determine that an instruction signal according to an operation to the pointing stick is different from the cursor movement instruction signals when each of outputs from the +X sensor, −X sensor, +Y and −Y sensor is changed by a corresponding predetermined first threshold value or greater within a predetermined time period.
