PROBLEM TO BE SOLVED: To obtain an adhesive exhibiting a high elongation and linear expansion coefficient and also a suitable elasticity after its curing. SOLUTION: The adhesive is provided by containing a polymerizable component consisting of a specific acrylic oligomer and acrylic monomer, and a rubber component, and exhibiting not only a high linear expansion coefficient, elongation and softness after its curing by the polymerizable component but also a high elasticity after the curing by the rubber component. Therefore, in the case of elevating a surrounding temperature of a laminated material 10 obtained by pasting the objectives to be pasted 11, 17 having different linear expansion coefficients each other through an adhesive layer 15, a stress generated in the adhesive layer 15 caused by the difference of the different expansion coefficients is absorbed by the flexibility of the adhesive layer 15 itself. Also, even if the adhesive layer 15 is deformed, since the adhesive layer 15 restores to its original shape by the elasticity of the adhesive layer 15 itself, the positional discrepancy of the objects to be adhered 15, 17 does not occur.
