摘要

The present invention provides a windshield on which an information acquisition device that acquires information from outside of a vehicle by emitting and/or receiving light is disposable, the windshield including: a glass plate; and a heating wire that is provided on the glass plate and to which a current is applied. The glass plate includes at least one information acquisition region that faces the information acquisition device and through which the light passes, the heating wire includes a plurality of linear main body portions that pass through at least the information acquisition region and a linear linking portion for linking the plurality of main body portions, and at least one of the linking portions includes a heat generation suppressing means for suppressing heat generation when a current is applied.

說明書

With regard to Examples 1 to 11 and the comparative example described as described above, the temperatures of the heating wires at positions indicated by reference signs a, b, and c shown in FIGS. 9A and 9B were measured. Reference sign b indicates the vertex portion of the bent portion, and reference signs a and c indicate points on the linking portion that are located 35 mm away from reference sign b. Also, as for each of the Examples 1 to 18, an average temperature s of the temperatures taken at a and c, the temperature taken at b, and a temperature difference dT therebetween were each calculated. The results are as follows.
