PROBLEM TO BE SOLVED: To provide a compact material testing device for structurally preventing generation of sliding resistance. SOLUTION: The compact material testing device 1 is provided with a fixed side holding means 4 for holding an end side of a specimen 2, a load shaft 5, capable of moving in the axial direction, for holding another side of the specimen 2, a distortion detecting means 6 attached to a load shaft 5, a supporting means 7 for supporting a load shaft 5 movable in its axial direction and a piezoelectric actuator 9 connected to the load shaft 5 via a connection member 8. The supporting means 7 has a pair of rocking bodies 10 which are rockably attached to a testing table 3 in the axial direction of the load shaft 5 at a same height in parallel and supports the load shaft 5 movable in the axial direction by connecting upper ends of the pair of rocking bodies 10 at two positions apart in the axial direction of the load shaft 5. The piezoelectric actuator 9 is positioned in parallel to the load shaft 5 and applies load to the specimen 2 by moving the load shaft 5 together with a connection member 8 by expansion and contraction action of the piezoelectric actuator 9.
