Abstract: A copolymer contains a (meth)acrylic based monomer unit A having an anionic group, a (meth)acrylic based monomer unit B having a cationic group, and a (meth)acrylic based monomer unit C other than the (meth)acrylic based monomer unit A and the (meth)acrylic based monomer unit B, and the (meth)acrylic based monomer unit C has a weight average molecular weight of 2,000 to 9,000. The surfactant contains the copolymer. The resin composition contains a resin, the surfactant, and an inorganic filler. The heat dissipation sheet contains the resin composition. The present invention can provide a copolymer that is capable of reducing the viscosity of a resin composition containing a resin and an inorganic filler, a surfactant containing the copolymer, a resin composition containing the surfactant and an inorganic filler, and a heat dissipation sheet containing the resin composition.
