This invention provides a pointing device which gives a feeling of operation closer to the feel of people without requiring an operation space. While a writing instrument having a pen grip (2) fitted thereto is held by a hand, a gripping force is applied by fingers as if a line were drawn in a moving direction of a cursor (the line need not be drawn in practice). The pressures of the fingers are measured by strain gauges (28a, 28b, and 28c), which send their corresponding voltage values to a CPU (40). The CPU (40) calculates the moving direction and distance of the cursor on the basis of the voltage values. Then, receiving the data, the cursor is moved to a designated position. When a microswitch (110) is pushed, the cursor position is made definite.
