Provided are a variety of useful applications that make the most of characteristics of an all-solid-state cell in which an oriented polycrystalline body is used as a positive electrode active material; the characteristics, in particular, being advantages such as small size, high energy density, and high degree of safety. Use of an all-solid-state cell in at least one application selected from sensors, smartcards, radio-frequency identification (RFID), wearable devices, portable terminals, tracking systems, radiation monitors, energy-harvesting power sources, medical applications, cordless drills and other electrical machine tools, and 3G shields and the like; the cell being provided with: a positive electrode layer having a positive electrode active material, the positive electrode active material being an oriented polycrystalline body comprising a plurality of lithium transition metal oxide particles oriented in a fixed direction; a solid electrolyte layer comprising a lithium-ion-conducting material; and a negative electrode layer having a negative electrode active material. |
