切断してフッ素樹脂プリプレグ５を得る方法である。A method for manufacturing a prepreg according to the first invention is schematically shown in the cross-sectional view of FIG. A fluororesin film 2 made of fluororesin is tightened and integrated on the top and bottom of a glass cloth 1, which is the base material of the prepreg, with a pressure roll 3 set to apply a linear pressure of about 100 kg/d. This is a method of obtaining a fluororesin prepreg 5 by cutting it into lengths with a cutting device 4.

This is a method of heating to ~400°C. For this reason,
In order to heat and melt the fluororesin film 2 bonded to the surface of the glass substrate with this pressure roll 3 and pressurize it,
It is possible to obtain a fluororesin prepreg in which the fluororesin sufficiently penetrates into the glass cloth base material.
第３の発明のプリプレグの製法は、基本的には第１図の
