There are provided a light emitting device and an electronic device, which are light, have low consumption power and a low cost. When an organic light emitting material (1204b) is included in the positions between the lattices of a heavy metal complex (1204a) with a lattice structure, the phosphorescence of the organic light emitting material (1204b) in which only fluorescence is generally observed can be promoted. Since the organic EL element obtained thus can utilize phosphorescence, the light emission efficiency is high. Also, since a conventional organic light emitting material can be used, various light emission colors are obtained and the organic EL element can be manufactured at a low cost. A light emitting device and an electronic device are manufactured using such an organic EL element.
