A rise in temperature of a work (laminating base material) is controlled and the occurrence of thermal deformation is suppressed. There is provided a three-dimensional laminating and shaping apparatus having the following arrangement. That is, the three-dimensional laminating and shaping apparatus includes a material ejector that ejects a material of a three-dimensional laminated and shaped object onto a work on which the three-dimensional laminated and shaped object is shaped. The three-dimensional laminating and shaping apparatus includes a light beam irradiator that irradiates the ejected material with a light beam. Furthermore, the three-dimensional laminating and shaping apparatus includes a jig to which the work is detachably attached. The jig includes a channel supplied with a cooling medium for cooling the work.
