1. Laminated glass, comprising:
a pair of glass plates facing each other;
an intermediate film positioned between the pair of glass plates;
an electrically conductive heating material positioned between the pair of glass plates and having a surface in contact with the intermediate film;
a first bus bar and a second bus bar connected to the electrically conductive heating material and positioned between the pair of glass plates, disposed such that the electrically conductive heating material is interposed between the first bus bar and the second bus bar in a plan view;
third bus bars at least partly positioned between the pair of glass plates, and connecting the first bus bar and the second bus bar to a pair of electrode leads; and
a fourth bus bar at least partly positioned between the pair of glass plates, and disposed so as to be superposed on an area of at least a part of at least one of the first bus bar, the second bus bar, and the third bus bars,
wherein the electrically conductive heating material, the first bus bar, the second bus bar, and the third bus bars are integrally formed of a same material, wherein the intermediate film includes, between the pair of glass plates, a first intermediate film having the electrically conductive heating material, the first bus bar, the second bus bar, and the third bus bars on a surface of the first intermediate film, and a second intermediate film laminated in contact with the first intermediate film.
