Abstract: A vehicle window glass includes: a curved glass plate having a first face and a second face; two bus bars that are formed on the first face and are respectively disposed along any two sides of the glass plate; a plurality of heating wires that are formed on the first face and are arranged in parallel to connect the bus bars to each other; and connection terminals that are respectively disposed on the two bus bars, in which the two bus bars each have a first region wherein the connection terminal is disposed, and a second region other than the first region, wherein the first region and the second region are linked along the corresponding side, and the width of the first region is the same as or smaller than the width of the second region.

Abstract: There are provided a method and apparatus capable of conveniently and rapidly inspecting a warpage of a rod. A rod to be inspected is rolled down an inspection bed and light shielded by the downwardly rolling rod is detected by a line sensor as a one-dimensional image signal. A positional fluctuation value of the downwardly rolling rod is obtained from a two-dimensional image signal obtained from the one-dimensional image signal. Based on the positional fluctuation value, the degree of the warpage of the rod is determined. The shielded light signal is detected in the vicinity of one end of the downwardly rolling rod to be inspected.
