PURPOSE: To provide a radiation shielding material which is hygienic, having high efficiency of radiation shielding, capable of being easily formed and processed at a low cost, easy to use and capable of being used at a movable part, and to provide a manufacturing method thereof.

CONSTITUTION: A radiation shielding material is constituted of a compound of particles of a material having a high radiation absorptivity, a resin and a plasticizer that imparts plasticity to the resin, whereby the particles are enclosed with the resin having the plasticity, then the material has, as a whole, the plasticity. The radiation shielding material is manufactured such that the particles of the material having the high radiation absorptivity, resin, plasticizer and a solvent are mixed to make a slurry, it is formed in a prescribed shape and the solvent is removed by drying.
