Abstract

Electrodes for a transparent electrically conductive film provided on a transparent panel of a shield panel have metal foils. The metal foils extend along the transparent electrically conductive film while electrically connected to the transparent electrically conductive film. Therefore, a resistance of each of the electrodes is low and potential drop is less prone to be caused in the electrodes. Thus, a voltage applied between the electrodes is effectively applied to the transparent electrically conductive film, and even if a power source voltage is not high, the transparent panel is effectively heated, and a defogging effect is high. As a result, it is possible to provide a shield panel having high defogging effect and less expensive manufacturing cost, and to provide a helmet having such a shield panel.
