摘要：
An object of the present invention is to provide a material which does not substantially have a hole injection barrier from an electrode. A composite material containing an organic compound and an inorganic compound, in which measured current-voltage characteristics of a thin-film layer formed from the composite material which is sandwiched between a pair of electrodes each having a work function of 3.5 eV to 5.5 eV follow Formula (1) below, is manufactured. J = { A exp ( - ϕ a 2 kT ) } V + BV n ( 1 )
