AI Technical Summary
Technical Problem
Existing laminates with metal and resin bodies face challenges in maintaining strong bonding strength due to thermal expansion differences, leading to stress and reduced durability.
Method used
Incorporating an adhesive layer made of thermoplastic resin or thermoplastic elastomer between the metal and resin bodies, with a molding shrinkage rate of 1.5% or less, to effectively absorb thermal shrinkage stress and improve bonding strength.
Benefits of technology
The laminate exhibits enhanced bonding strength and durability, particularly in high-temperature environments, by reducing stress from thermal shrinkage and maintaining cohesive force.

Abstract
To provide a laminate which can be improved in joining strength between a metal body and a resin body.SOLUTION: In a laminate 1, a metal body 2 and a resin body 3 are joined together. The laminate 1 is provided with an adhesive layer 4 containing a thermoplastic resin or a thermoplastic elastomer between the metal body 2 and the resin body 3. A molding shrinkage rate of the adhesive layer 4 is 1.5% or less.SELECTED DRAWING: Figure 1
