To study characteristics of stress distribution in the conductor is necessary for the design of a superconducting magnet working stably at high magnetic fields. Strain effects of conductors depend on the layer thickness of Nb3Sn filaments and the structure of the conductor. The dependence of reversible strain and pre-strain effects on the layer thickness were investigated using superconductor fabricated by liquidus-solidus process that could vary the layer thickness of Nb3Sn in the wide range. The reversible strain limit decreased with increasing Nb3Sn layer thickness. It was found that the pre-strain of the conductors depended on how Nb3Sn filaments were grouped and distributed in the stabilizer like Cu.
