PROBLEM TO BE SOLVED: To provide a polymer actuator that is small in size, light in weight, can be accommodated into a limited space, and is increased in deformation amount, and to provide an articulated hand robot that is small in size, light in weight, high in the flexibility of shape, and can be operated flexibly and handily. SOLUTION: The polymer actuator 1 is increased in deformation amount, by accommodating a polymer membrane 11 longer than the length of the accommodating space 4 into space by winding, for example, one end of the polymer membrane 11 and/or folding the membrane into a meandering shape or a bellows shape. The articulated hand robot can accommodate the polymer actuator in its fingers and hands, can increase the folding angle at a joint while being small in size and light in weight, can be operated flexibly and dextrously, and can effectively especially be adapted to hands of a robots for support for living and entertainment robots, in particular.
