Abstract

A mercury emitter realizing an enhancement of mercury emission efficiency. Mercury emitter (100) comprises mercury emission part (10) consisting of a mercury alloy containing mercury (Hg) and at least one first metal selected from the group consisting of titanium (Ti), tin (Sn), zinc (Zn) and magnesium (Mg) and, provided so as to cover the mercury emission part (10), sintered material layer (20) from a material containing at least one second metal selected from the group consisting of iron (Fe) and nickel (Ni).
