The present disclosure provides a method for manufacturing a vehicle windshield capable of improving the breaking strength after a terminal is attached. A method for manufacturing a vehicle front window glass, in which the vehicle front window glass includes a terminal-equipped glass plate having a glass plate, an electric conductor made of a material containing silver and a glass frit and having a terminal joint portion, and a terminal joined to the terminal joint portion of the electric conductor by means of a lead-free solder, the production method comprises: a step (S2) for applying a silver-containing paste containing silver and a glass frit as a material for a conductor on a glass plate as a material for a terminal-equipped glass plate; a step (S3) for forming a conductor by firing the glass plate coated with the material of the conductor; a step (S5) for polishing the surface of a region including the terminal joining part of the conductor; and a step (S6) for bonding a terminal to the terminal bonding portion, the surface of which has been ground, by means of a lead-free solder, in which the porosity of the terminal bonding portion of the conductor after the step (S5) is 10% or less.
本公开提供能够提高端子安装后的破坏强度的车辆用前窗玻璃的制造方法。一种车辆用前窗玻璃的制造方法,其中车辆用前窗玻璃包括带端子玻璃板,该带端子玻璃板具有玻璃板、由包含银和玻璃料的材料构成且具有端子接合部的导电体、以及藉由无铅焊料接合到该导电体的端子接合部上的端子,上述制造方法包括:在作为带端子玻璃板的材料的玻璃板上涂布作为导电体的材料的包含银和玻璃料的含银糊料的工序(S2);对涂布有导电体的材料的玻璃板进行烧成以形成导电体的工序(S3);对导电体的包括端子接合部的区域的表面进行研磨的工序(S5);以及藉由无铅焊料将端子接合到表面经研磨的端子接合部上的工序(S6),其中,工序(S5)后的导电体的端子接合部的孔隙率在10%以下。
