    Abstract: A stress reducing agent that is excellent in dispersibility in a matrix resin and enables provision of a cured product having a favorable linear expansion coefficient is provided. The stress reducing agent contains fine polymer particles (A). The particles (A) contain a rubber-containing graft copolymer including an elastic body and a graft part grafted to the elastic body. The elastic body contains an organosiloxane-based rubber. The elastic body is contained in an amount of above 70 wt % and 97 wt % or less, relative to 100 wt % of the particles (A). The graft part contains an epoxy group-containing structural unit. The epoxy group-containing structural unit in the graft part is contained in an amount of 0.5-4.0 wt % with respect to 100 wt % of the rubber-containing graft copolymer. The stress reducing agent is a powdery and/or granular material.
