An intervertebral cage having flexibility is provided wherein a housing itself has a plate spring form having proper elasticity. The housing can have a shape memory characteristic to obtain a modulus of elasticity suitable for differing spinal loads according to each patient, thereby absorbing a shock applied to a spine. A distance between disks is restored by the intervertebral cage to sufficiently secure a disc height, thereby relieving spinal nerve stress. The intervertebral cage may be converted from a simple fusion application into a functional cage adequate for a physiological biomechanics. The flexible intervertebral cage includes a housing having a closed sectional surface with an empty hollow therein. The housing itself has proper elasticity so that it absorbs a load by a stress applied in a vertical direction of a spine by a dynamic motion due to an upright walk of a patient to serve as a normal disk.
