Patent ID: 8007693

Claim:
A zinc oxide transparent electric conductor having zinc oxide (ZnO) as its principal component, containing an element to become an n-type dopant to zinc oxide, containing metal M in which P(P=(ΔG 0 +ΔHx(M))/RT, wherein ΔG 0 is the standard free energy change of redox reaction of metal M and zinc oxide, ΔHx(M) is the heat of dissolution of zinc as a constituent metal element of zinc oxide to metal M, R is the gas constant, and T is the temperature) as a parameter showing the wettability with zinc oxide is 6 or less and in which its resistivity is smaller than the resistivity of zinc oxide added with the n-type dopant, and wherein concentration of metal M in relation to the total atomicity of zinc and the n-type dopant and metal M, which are all metal atoms configuring the zinc oxide transparent electric conductor, is 0.05 to 2.0 at %.
