Abstract: A method may produce a perovskite-type ceramic compact including a perovskite-type ceramic having an alkaline earth metal element, at least one element selected from Ti, Zr, and Hf, and O. Such a method may include a contact reaction process in which a precursor compact including singly a gel including water and an oxide of at least one element selected from Ti, Zr, and Hf, and a liquid containing a hydroxide of the alkaline earth metal element are brought into contact with each other.
