ABSTRACT:
The dislocation between each layer in a multi-layer circuit board and a process for producing the same and an application of the same is minimized by employing a specific adhesive layer between layers of the circuit board. The adhesive layer is composed of a film of a resin having a melting point higher than a temperature for forming the multi-layer (or laminated layer) circuit board and adhesive having a melting point lower than the temperature for forming the multi-layer circuit board.
