A method for bonding a first body ( 2 ) to a second, panel-shaped body ( 3 ) at bonding surfaces ( 2 a, 3 a ) lying opposite each other, the second body ( 3 ) projecting in at least one direction (X) beyond an edge ( 2 ′) of the first body ( 2 ). The method includes: producing a plurality of spacers ( 4 a to 4 e, 4 a ′ to 4 e ′) on at least one of the bonding surfaces ( 2 a ), applying adhesive ( 5 ) into intermediate spaces ( 6 a to 6 d ) between the spacers beyond an outer spacer ( 4 e, 4 e ′) as far as an adhesive periphery ( 5 a ), which is formed at an edge ( 2 ′) of the first body ( 2 ), and bonding the bodies ( 2, 3 ) by bringing the bonding surfaces ( 2 a, 3 a ) into contact at the spacers ( 4 a ′ to 4 e ′). A prescribed distance (d) between the adhesive periphery ( 5 a ) and the outermost spacer ( 4 e ) is set to provide a desired state of deformation of the panel-shaped body ( 3 ) after a shrinkage of the applied adhesive ( 5 ) (e.g. minimized bending of the body.) In an associated composite body ( 1 ), the prescribed distance (d) lies between 20 μm and 250 μm, preferably between 30 μm and 200 μm, in particular between 40 μm and 150 μm.
