Abstract
A heat-generating plate that generates heat when a voltage is applied, including a pair of glasses, a pair of bus bars to which the voltage is applied, and a heat-generating conductor that can couple between the pair of bus bars. The heat-generating conductor includes a plurality of conductive thin wires that linearly extends between the pair of bus bars and couples between the pair of bus bars. An average Wof a width W of one of said conductive thin wires is within a range of the following formula(a) relative to a standard deviation σ of distribution of the width W: 0≤4σ/W≤0.3 (Formula(a)).
