Abstract

This invention provides a ceramic powder capable of forming a sintered body having a high density and high ionic conductivity even at a sintering temperature lower than the temperature conventionally used, and provides a battery containing a sintered body of the ceramic powder as a constituent element. The above problem is solved by a ceramic powder containing a garnet-type oxide and compound 1, wherein the garnet-type oxide contains zirconium, lithium, and lanthanum, and compound 1 contains at least one metal element selected from the group consisting of lanthanum, lithium, zirconium, gallium, scandium, yttrium, cerium, aluminum, calcium, magnesium, barium, strontium, niobium, and tantalum.
