Claim:
1. A method for producing a garnet-type compound, the method comprising: (1) a first step of mixing a first raw material and a second raw material to obtain a precipitate, the first raw material being a solution comprising a zirconium carbonate complex and having a pH of at least 7.0 and not more than 9.5, the second raw material comprising a compound containing the above element M (2) a second step of mixing the precipitate and a third raw material to obtain a mixture, the third raw material containing Li as a constituent element, and then firing the mixture at a temperature of less than 1,000° C. to obtain a fired product, the first raw material being a solution prepared in such a manner that the molar ratio of carbonate species to zirconium species: (number of moles of carbonate species)/(number of moles of zirconium species) is in the range of 1.5 or more to 15.0 or less, at least one of counter ions of the zirconium carbonate complex being NR wherein the garnet-type is defined as a compound comprising Zr, Li, and element M
