Material for organic electroluminescence device and organic electroluminescence device

A material in a solid state, said material being for an organic electroluminescence device, comprising:

• an organometallic compound that is to be provided for a dry film formation process of any of at least one organic layer included in the electroluminescence device, wherein the material has a water content before the dry film formation process, as measured by the Karl Fischer method, of 100 ppm or more and not more than 1,000 ppm,
• wherein the organometallic compound is an iridium complex represented by the following formula (E-1):
• in the formula (E-1), each of Z1 and Z2 independently represents a carbon atom;
• A represents an atomic group for forming a 6-membered aromatic ring together with Z1 and N;
• B represents an atomic group for forming a 6-membered aromatic ring together with Z2 and C;
• though each of a line connecting Z1 and N, a line connecting Z1 and the atomic group A, a line connecting N and the atomic group A, a line connecting Z2 and C, a line connecting Z2 and the atomic group B and a line connecting C and the atomic group B is expressed by a single line, each may be either a single bond or a double bond irrespective of a bonding species;
• and
• n represents an integer of 3.
