Abstract
A bonding sheet includes a pair of bonding agent layers and a plurality of thermal conductors each having a linear shape. The pair of bonding agent layers are formed using a resin composition and face each other. One end of each of the plurality of thermal conductors is covered with one of the pair of bonding agent layers, and another end of each of the plurality of thermal conductors is covered with another of the pair of bonding agent layers. The resin composition contains (A) a thermosetting resin, (B) a thermoplastic resin having a glass transition temperature of 50° C. or more, and (C) a thermoplastic resin having a glass transition temperature of less than 50° C.
