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):
wherein M is a metal atom; each R
0
independently represents a divalent linking group; i and j each independently represent 0 or 1; 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):
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.
