To solve a problem wherein it is not easy to provide a conveyance device capable of being installed even in a place of an inflexible shape of a transportation pipe, a curved part, and a place requiring flexibility and requiring no space for installing a power source.

This peristaltic movement conveyance device has the transportation pipe 1 having flexible expansion and contraction properties and a bidirectional shape memory alloy 2. The bidirectional shape memory alloy 2 is attached to a surface of the transportation pipe 1. When heating the bidirectional shape memory alloy 2 by carrying current into it, transportation passage cross sectional area of the transportation pipe 1 is also contracted by contraction force of the alloy. When releasing current carried into the bidirectional shape memory alloy 2, the transportation passage cross sectional area of the transportation pipe 1 is also restored to an original condition by restoration force of the alloy. A position for applying contraction and restoration on the transportation pipe 1 is sequentially moved in the fixed direction by a temperature controller to convey an object in the transportation pipe 1 in the fixed direction.
