To apply a load in the bent state, because of being bendable not only in the extending/contracting direction of a specimen but also in a plurality of directions.
This testing device is equipped with the first driving mechanism for extending/contracting an extending/contracting part of the specimen, the first holding means for holding the extending/contracting part of the specimen mounted on the first driving mechanism through an elastic body, the second holding means for holding a specimen body, a rotation driving mechanism for rotating the second holding means by using the extending/contracting direction of the extending/contracting part as an axis, a stage for fixing the rotation driving mechanism, and the second driving mechanism for bending the extending/contracting part of the specimen through the stage.
