Abstract
A bonding sheet that can be bonded with a metal foil by thermal lamination and has excellent adhesiveness and reduced warpage, and a one-side metal-clad laminate are provided. A bonding sheet has an adhesive layer containing a thermoplastic resin disposed on one side of a heat resistant film and a non-adhesive layer containing a non-thermoplastic resin and a thermoplastic resin disposed on the other side of the heat resistant film. The ratio of the non-thermoplastic resin to the thermoplastic resin in the non-adhesive layer is 82/18 to 97/3 on a weight basis.
