Description of the Related Art A composite laminate is prepared by coating an intermediate resin layer on a glass cloth, placing a glass nonwoven fabric thereon, stacking two obtained prepregs with the glass nonwoven fabric inside, and applying heat and pressure. In the production method of (1), there is a problem that the resin adheres to the prepreg production facility, which breaks the glass cloth, making it impossible to produce the prepreg stably, thereby lowering the productivity. As a method for preventing the exudation of the intermediate layer resin, it is known that a glass cloth is impregnated with an epoxy resin and dried. When the glass cloth is impregnated only with the epoxy resin, it must be sufficiently dried after the impregnation in order to prevent the intermediate layer resin from seeping out from the opposite side of the glass cloth. For this reason, in the obtained composite laminate, the adhesion between the copper foil and the prepreg tends to decrease. On the other hand, in the case where the glass cloth is impregnated with an epoxy resin to which an inorganic filler or the like has been added, if the amount and the particle size of the inorganic filler and the like are not appropriate, the bleeding of the interlayer resin cannot be sufficiently prevented,
On the contrary, even if the bleeding can be prevented, there is a problem that the punching property of the laminate is reduced.

が抜け落ちることを防止する。DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the present invention, an epoxy resin containing 1 to 5% by weight of a particulate inorganic filler is impregnated into a glass cloth so that the punching property of a laminate is not reduced, and an intermediate time during the production of a prepreg is reduced. This is to prevent the layer resin from exuding from the opposite side of the glass cloth. Conventionally, in the case of a method for producing a composite laminate having a step of applying an intermediate layer resin on a glass cloth, as a method of preventing the intermediate layer resin from exuding from the glass cloth, the glass cloth is impregnated with an epoxy resin. In the method, the epoxy resin is weakly caught by the textured voids of the glass cloth, and the interlayer resin falls out of the textured voids of the glass cloth together with the epoxy resin previously impregnated into the glass cloth. In the present invention, by adding 1 to 5% by weight of the particulate inorganic filler to the epoxy resin impregnated into the glass cloth, the particulate inorganic filler is caught in the textured voids of the glass cloth and fills the voids. Prevents the interlayer resin from falling off.

なる。特に好ましい範囲は２００〜７００ｎｍである。When more than 5% by weight of a particulate inorganic filler is added to an epoxy resin impregnated in a glass cloth, the particulate inorganic filler is crosslinked at the interface between the interlayer resin and the epoxy resin impregnated in the glass cloth. Hinder the structure,
The adhesiveness between the intermediate layer resin and the glass cloth impregnated with the epoxy resin is weakened, and the punching property is reduced. If the content is less than 1% by weight, a sufficient effect cannot be obtained because the interlayer resin does not exude from the opposite surface of the glass cloth. In order to achieve the object of the present invention, the fine particle inorganic filler preferably has an average particle diameter of 100 nm to 100 μm. 100nm
If it is smaller, the viscosity of the varnish to be impregnated becomes high, handling becomes difficult, and the impregnating property to the glass cloth also decreases. If it is larger than 100 μm, the effect of preventing seepage from the glass cloth is reduced. A particularly preferred range is from 200 to 700 nm.
