From Table 1, it was confirmed that the temperature of the electrical connection portion 806 is decreased by providing the widened portion 802. Since the temperature rise of the glass plate 1201 occurs when the heat of the electrical connection portion 806 is transmitted to the glass, it was confirmed from the measurement results in Table 1 that the temperature rise of the edge portion of the glass plate 1201 can be reduced.
- the disclosed electrical connection member and a laminate using the electrical connection member can be suitably used particularly when power is supplied to electrical functional parts such as an antenna conductor and a bus bar conductor enclosed in a laminated glass.
