Abstract
Provided is an organic electroluminescence device material, which, in its production, is free from formation of impurities that worsen the performance of organic EL devices, which, in forming an upper layer by coating, does not cause dissolution mixing or swelling mixing, which forms a film of good quality and which contributes toward improving the performance (high durability, and low driving voltage) of organic EL devices. The organic electroluminescence device material is a siloxane compound having a recurring unit represented by the following general formula (1):
