Disclosed is an electrochemiluminescence cell that can have high durability by obtaining sufficiently uniform surface light emission. In an electrochemiluminescence cell having a light emitting layer 12 and electrodes 13 and 14 disposed on each surface thereof, the light emitting layer includes an organic polymer light emitting material and an ionic liquid, and the ionic liquid is represented by the following general formula. An electrochemiluminescence cell represented by (1). In the formula, M represents N or P. R 1 , R 2 , R 3 and R 4 represent a saturated aliphatic group, unsaturated aliphatic group or aromatic ring-containing group having up to 20 carbon atoms. X − is an anion. [Selection] Figure 2 |
