<P>PROBLEM TO BE SOLVED: To provide a displacement conversion device that uses a Pascal's principle and is hardly affected by temperature change. Ž<P>SOLUTION: A device body 1 includes a housing space 11 for housing a medium 2 therein. The medium 2 includes a fluid body 21 having a positive thermal expansion coefficient and a movable body 22 having a negative thermal expansion coefficient. The movable body 22 is displaced along with movement of the fluid body 21. The medium 2 has a first movable surface 23 having a small area and a second movable surface 24 having a large area. Displacement of one of the first movable surface 23 and the second movable surface 24 is transmitted to the other via the medium 2. In the displacement conversion device, even when the volume of the fluid body 21 varies due to temperature change of the medium 2, a fluctuation amount of the entire volume of the medium 2 can be suppressed to be lower by change in the volume of the movable body 22.
