1. A laminated glass for a vehicle, the laminated glass having an intermediate film between an outer glass plate and an inner glass plate, comprising:
a test area A defined by JIS Standard R3212;
an information transmitting/receiving area in which a device installed in a vehicle transmits and/or receives information; and
a film capable of heating the information transmitting/receiving area, the film being adhered to an area that is outside of the test area A and overlaps the information transmitting/receiving area in a planar view between the intermediate film and either one of the outer glass plate or the inner glass plate, wherein the film comprises a substrate, a planar heating element on a surface of the substrate, and a busbar connected to the heating element, the planar heating element conforms to a shape of the surface of the substrate, the planar heating element covers the entirety of the surface of the substrate except for at least one slit, each of the at least slit extends through a thickness of the planar heating element in a direction perpendicular to the surface of the substrate, the planar heating element is divided into two or more planar heating areas by the at least one slit, the two or more planar heating areas share at least one busbar and are connected in series, and each of the at least one slit has a width of 0.3 mm or less in a direction parallel to the surface of the substrate.
