Abstract
A method for producing multi-layer printed board. The method includes heating a hole board as a top layer, an adhesive sheet, and a bottom layer board. The adhesive sheet includes a mold release sheet and a thermoplastic resin sheet which begins to soften at a temperature lower than the melting temperature of the adhesive. A contraction control member controls contraction when the thermoplastic resin sheet cools.
