Abstract
The electrochemical cell includes an anode, a cathode active layer, and a solid electrolyte layer disposed between the anode and the cathode active layer. The cathode active layer includes a first region which is disposed facing the solid electrolyte layer, and a second region which is disposed on the first region. An average particle diameter of first constituent particles which constitute the first region is smaller than an average particle diameter of second constituent particles which constitute the second region.
