The purpose of the present invention is to provide: a vehicle-windshield-glass intermediate film which makes it possible to produce a vehicle windshield glass with high yield by using a vacuum degassing method, and which has concavities formed in a ruled-line pattern; a rolled body of said vehicle-windshield-glass intermediate film; and a vehicle windshield glass which uses said vehicle-windshield-glass intermediate film. The present invention pertains to a vehicle-windshield-glass intermediate film having a plurality of concavities and a plurality of convexities on one or more surfaces thereof, wherein: the floor sections of the concavities have a continuous groove shape; adjacent concavities are regularly arranged in parallel with one another; and furthermore, the slope of the groove-shaped concavities having continuous floor sections is 35 degrees or more relative to the direction of flow of the film when producing the vehicle-windshield-glass intermediate film.

    本发明的目的在于,提供虽然具有刻线状的凹部然而能够利用真空脱气法以高成品率制造汽车用挡风玻璃的汽车用挡风玻璃用中间膜、该汽车用挡风玻璃用中间膜的辊状体、以及使用了该汽车用挡风玻璃用中间膜的汽车用挡风玻璃。本发明提供一种汽车用挡风玻璃用中间膜,是在至少一个表面具有多个凹部和多个凸部、所述凹部具有底部连续的槽形状、相邻的所述凹部平行且规则地并列的汽车用挡风玻璃用中间膜,所述底部连续的槽形状的凹部的倾斜度相对于该汽车用挡风玻璃用中间膜制造时的膜的流送方向为35°以上。
