1. An electroluminescence light emitting sheet comprising:

  • a light-emitting layer containing electroluminescence light-emitting elements therein; and

    an electrode section including a plurality of electrode pairs which are disposed with a predetermined arrangement, wherein each of the electrode pairs includes first and second electrodes which are electrically separated from each other with a spacing region and disposed on one surface side of the light-emitting layer with a predetermined arrangement, wherein, when an electrically conductive material is placed on another surface side of the light-emitting layer which is opposite to the one surface side, the electrode section forms a closed circuit between the conductive material and at least one of the electrode pairs receiving an application of AC voltage, through the light-emitting layer.
