A shape memory morphing member using a kirigami pattern, the shape memory morphing member extending in a length direction and a width direction and comprising: an upper shape memory polymer skin layer extending in the length direction and the width direction; a lower shape memory polymer skin layer which is disposed below the upper shape memory polymer skin layer and extends in the length direction and the width direction; and a core which is interposed between the upper shape memory polymer skin layer and the lower shape memory polymer skin layer and has a kirigami pattern structure arranged in the length direction and the width direction of the morphing member, the kirigami pattern structure including multiple kirigami pattern rows which extend in the width direction, wherein the upper shape memory polymer skin layer and the lower shape memory polymer skin layer have a restoring force that restores the upper shape memory polymer skin layer and the lower shape memory polymer skin layer to initial shapes in a first state at a higher temperature than a predetermined temperature, the upper shape memory polymer skin layer and the lower shape memory polymer skin layer have a degree of freedom of deformation corresponding to an external force to be combined with the restoring force, and the shapes of the upper shape memory polymer skin layer and the lower shape memory polymer skin layer in the first state before switching to a second state are maintained in the second state at a lower temperature than the predetermined temperature, characterized in that the kirigami pattern rows extend while being bent multiple times and have crests and troughs alternately formed in the width direction, and one of the multiple kirigami pattern rows is formed such that a crest part of the one of the multiple kirigami pattern rows is hingedly coupled to a crest part of another kirigami pattern row which is adjacent to the one of the multiple kirigami pattern rows in one direction of the length direction, and a trough part of the one of the multiple kirigami pattern rows is hingedly coupled to a trough part of another kirigami pattern row which is adjacent to the one of the multiple kirigami pattern rows in the other direction of the length direction. an upper shape memory polymer skin layer extending in the length direction and the width direction; a lower shape memory polymer skin layer which is disposed below the upper shape memory polymer skin layer and extends in the length direction and the width direction; and a core which is interposed between the upper shape memory polymer skin layer and the lower shape memory polymer skin layer and has a kirigami pattern structure arranged in the length direction and the width direction of the morphing member, the kirigami pattern structure including multiple kirigami pattern rows which extend in the width direction, wherein the upper shape memory polymer skin layer and the lower shape memory polymer skin layer have a restoring force that restores the upper shape memory polymer skin layer and the lower shape memory polymer skin layer to initial shapes in a first state at a higher temperature than a predetermined temperature, the upper shape memory polymer skin layer and the lower shape memory polymer skin layer have a degree of freedom of deformation corresponding to an external force to be combined with the restoring force, and the shapes of the upper shape memory polymer skin layer and the lower shape memory polymer skin layer in the first state before switching to a second state are maintained in the second state at a lower temperature than the predetermined temperature, characterized in that the kirigami pattern rows extend while being bent multiple times and have crests and troughs alternately formed in the width direction, and one of the multiple kirigami pattern rows is formed such that a crest part of the one of the multiple kirigami pattern rows is hingedly coupled to a crest part of another kirigami pattern row which is adjacent to the one of the multiple kirigami pattern rows in one direction of the length direction, and a trough part of the one of the multiple kirigami pattern rows is hingedly coupled to a trough part of another kirigami pattern row which is adjacent to the one of the multiple kirigami pattern rows in the other direction of the length direction.
