The present disclosure provides a front window glass for a vehicle, which can be designed to include a portion where a conductor and a terminal are joined using a lead-free solder, in which a power feeding portion of the conductor is not seen by a person outside the vehicle, and in which the breaking strength of a glass plate after the terminal is mounted can be improved. A front window glass (1) for a vehicle includes a laminated glass (10) including a first glass plate (11) and a terminal-equipped glass plate (13X) having a second glass plate (13), a conductor (20) having a terminal bonding portion (20T), and a terminal (102) bonded to the terminal bonding portion (20T) by a lead-free solder (101), a power feeding part including a terminal bonding part (20T) is directly formed on the second glass plate (13), a first light shielding layer (BL1) covering the power feeding part of the conductor (20) is formed on the first glass plate (11), and a second light shielding layer (BL2) covering at least part of the conductor (20) except the power feeding part is formed on the terminal-equipped glass plate (13X).
本公开提供一种车辆用前窗玻璃,其可以设计为包含使用无铅焊料将导电体和端子接合的部分、且导电体的馈电部不会被车外的人看到,并且能够提高端子安装后的玻璃板的破坏强度。车辆用前窗玻璃(1),其包括包含第一玻璃板(11)和带端子玻璃板(13X)的夹层玻璃(10),该带端子玻璃板(13X)具有第二玻璃板(13)、以及具有端子接合部(20T)的导电体(20)和通过无铅焊料(101)接合在端子接合部(20T)上的端子(102),在导电体(20)中,包含端子接合部(20T)的馈电部直接形成在第二玻璃板(13)上,在第一玻璃板(11)上形成覆盖导电体(20)的馈电部的第一遮光层(BL1),在带端子玻璃板(13X)上形成覆盖导电体(20)的除馈电部以外的至少一部分的第二遮光层(BL2)。
