<p>The actuator (1) has a heating element (5) that heats shape memory element (4) when heating element is activated so that shape of shape memory element is changed. The heat conducting element (6) is in contact with shape memory element. The contact surface of heat conducting element is set larger than 0.1 times of total surface of shape memory element. The heat conducting element is provided with a free surface that does not contact with either the shape memory or heating elements. The free surface is set 1.6 times larger than contact surface.</p> |
