The invention of the present application refers to a composition capable of forming a heat-dissipation member having high thermal conductivity, and a heat-dissipation member. The composition for the heat-dissipation member of the present application contains a polymerizable liquid crystal compound having, at both terminals, a structure including an oxiranyl group or an oxetanyl group; a curing agent that cures the polymerizable liquid crystal compound; and an inorganic filler formed of nitride. A curing temperature of the composition for the heat-dissipation member is within or higher than the temperature range in which the polymerizable liquid crystal compound exhibits a liquid crystal phase, and within or lower than the temperature range in which the polymerizable liquid crystal compound exhibits an isotropic phase. The heat-dissipation member formed of such a composition can have excellent thermal conductivity owing to a synergistic effect between alignment of the liquid crystal compound and the inorganic filler formed of nitride.
