製造できる点で生産性の高いものである。2. Description of the Related Art Conventionally, a continuous production method of a metal foil-clad laminate is performed by impregnating a long base material such as glass cloth or paper with a varnish of a thermosetting resin, and impregnating the thermosetting resin in this process. Long copper foils transferred along a plurality of long base materials were laminated via a roll into a laminated band, and while the laminated band was sequentially sent to a curing furnace, the thermosetting property in the laminated band was changed. It is highly productive in that a resin can be cured by heating and a laminate can be continuously produced without applying pressure.
【０００３】しかしこのような連続工法は、加熱硬化炉
において加圧を伴わないため熱硬化性樹脂は、基材に対
して比率が小さく、得られる積層板は、緻密性が低い。
その結果水分が積層板内に吸収され易く、吸湿後の耐熱
性（ＰＣＴ特性）が低下する。[0003] However, such a continuous method does not involve pressurization in a heat-curing furnace, so that the ratio of the thermosetting resin to the base material is small, and the resulting laminated board has low denseness.
As a result, moisture is easily absorbed into the laminate, and heat resistance (PCT characteristics) after moisture absorption is reduced.

A metal foil-clad laminate with a thermosetting resin adhesive layer of about 0 μm has been produced, but the thermosetting resin adhesive layer has the impact resistance, heat cycle resistance and tracking resistance of the laminate. It is an inhibiting factor.
