    Patent number: 10808152
    Abstract: The present invention aims to provide an adhesive composition which enables achievement of highly strong adhesion between a lightweight composite resin and a lightweight metal member, and which can maintain excellent adhesive strength even in cases where the ambient temperature largely changes or the adhesive composition is in contact with water or a snow-melting agent, and an adhesive sheet using it. The above object can be achieved with an adhesive composition containing at least an epoxy resin, an acrylic particle, and a curing agent, wherein the acrylic particle is a core-shell structure containing a butadiene-based rubber, and polymethacrylate or polyacrylate. The adhesive sheet is constituted such that an adhesive layer formed with the adhesive composition is present between a first release film and a second release film.
