<p>A viscoelastic characteristic value-measuring apparatus, using a split Hopkinson bar, having an input bar (3) which is hit with an impact bar and on which a first strain gauge (7) and a second strain gauge (9) are installed; and an output bar (5) which is connected with the input bar (3) through a specimen and on which a third strain gauge (11) and a fourth strain gauge (13) are installed. The length of the input bar is set to a range from 1500mm to 2500mm both inclusive. <IMAGE></p>
