A highly stable metal complex useful for the manufacture of a light-emitting device has an excellent lifetime property, particularly in a blue region, specifically a metal complex represented by Formula (1): n nwherein M is a metal atom; each R 0 independently represents a divalent linking group; i and j each independently represent 0 or 1; R P1 , R P2 , R P3 , R P4 , R P5 and R P6 each independently represent a hydrogen atom and the like, with a proviso that at least one of R P1 , R P2 , R P3 , R P4 , R P5 and R P6 is a dendron; m is an integer of from 1 to 3, n is an integer of from 0 to 2, and m+n is 2 or 3; and the portion represented by Formula (2):n n n n n n n n n n n represents a bidentate ligand; wherein R x and R y are an atom bonding to the metal atom M, and each independently represents a carbon atom and the like. |
