Claim:
A transition metal complex compound [A] represented by Formula (I) below: wherein R 1 to R 6 are the same or different from each other and are each a hydrogen atom, a halogen atom, a hydrocarbon group, a heterocyclic compound residue, an oxygen-containing group, a nitrogen-containing group, a boron-containing group, an aluminum-containing group, a sulfur-containing group, a phosphorus-containing group, a silicon-containing group, a germanium-containing group or a tin-containing group, two or more of R 1 to R 6 may be linked to each other, and R 1 may be linked to Z; M is a transition metal atom of Group 3 to Group 10 of the periodic table; n is a valence of M; X is a hydrogen atom, a halogen atom, a hydrocarbon group, an oxygen-containing group, a sulfur-containing group, a nitrogen-containing group, a boron-containing group, an aluminum-containing group, a phosphorus-containing group, a halogen-containing group, a heterocyclic compound residue, a silicon-containing group, a germanium-containing group or a tin-containing group, the atoms or groups indicated by X may be the same or different from each other, and the groups indicated by X may be linked to each other to form a ring; Y is an oxygen atom, a nitrogen atom, a phosphorus atom or a sulfur atom; Z is a hydrocarbon group or a heterocyclic compound residue that may have a substituent group, and the minimum number of bonds linking Y with N is 5 or 6; the bond between Y and Z may be a double bond or a triple bond, and the bond between Y and R 1 may be a double bond or a triple bond; and the dotted lines each denote a coordination bond.
