Description of the Related Art A prepreg used for a printed wiring board is formed on a fiber base material such as woven or non-woven fabric such as paper, glass cloth, synthetic fiber or natural fiber, and phenol resin, epoxy resin, polyimide resin or polyamide resin. A liquid thermosetting resin (hereinafter, referred to as a liquid resin) is impregnated, the amount of the liquid resin adhered is adjusted by a squeeze roll or the like, and the liquid resin is semi-cured by heating and drying. Conventionally,
Examples of the method of impregnating the liquid resin include a dipping method in which the fiber base material is directly immersed in the liquid resin and impregnation, and a kiss method in which the fiber base material is brought into contact with a roll to which the liquid resin is adhered and indirectly impregnated through the roll. It has been known.

なるなどの課題がある。However, in the conventional impregnation method, if air bubbles remain in the prepreg, the surface of the prepreg will not be smooth after curing and an uneven surface will be formed, resulting in poor heat resistance. There is a problem that a stable prepreg cannot be obtained. In order to solve this problem, to improve the impregnation of the liquid resin into the fiber base material,
The time and distance of immersion in the liquid resin are set long, and the coating speed is set low. However, with such a method, productivity is low and the effect of removing bubbles is insufficient,
The surface smoothness of the prepreg is difficult, and the amount of the solvent must be increased in order to lower the viscosity.

いることが確認できた。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a fiber substrate 2 such as woven or non-woven fabric such as paper, glass cloth, synthetic fiber or natural fiber sent from a substrate supply device 1 by a feed roll 6 is used. While being in contact with the liquid resin 3 stored in the resin impregnating tank 4 attached to the ultrasonic vibrating device so as to vibrate, the liquid resin is impregnated with the impregnating roll 7 while applying ultrasonic vibration to pass at a predetermined speed. In the process in which the fiber base material 2 passes through the resin impregnation tank 4 due to this vibration,
Bubbles in the fiber base material 2 and deposits on the surface of the fiber base material 2 are removed, so that the fiber base material 2 can be impregnated with the liquid resin 3. Further, it is more effective to filter foreign matter removed in the resin impregnation tank 4 and circulate the liquid resin 3. Resin impregnation tank 4
Is subjected to a heat drying treatment by a dryer 5 to be a semi-cured prepreg. Using a resin impregnating apparatus shown in FIG. In addition, a ground was taken to eliminate the generation of static electricity due to vibration. In this state, the coating speed was set to 10 m / min and the liquid epoxy resin was impregnated. In the prepreg obtained by this resin impregnating apparatus, the proportion of bubbles per unit area when viewed from the top, that is, the bubble area ratio of the prepreg was 28%. As a comparative example, the ultrasonic vibration device was stopped, and a prepreg was manufactured under the same conditions. As a result, the bubble area ratio of the obtained prepreg was 48%. As is apparent from this, it was confirmed that the impregnating apparatus according to the present invention had a higher content of the liquid resin than the conventional one.
