Provided is an aluminum titanate-based ceramic having a small BET specific surface area and having a small pore volume when pulverized into a powder form in order to effectively use fine aluminum titanate-based ceramics. Preferably, a fine aluminum titanate ceramic, a titania source and an alumina source, optionally a precursor mixture mixed with a magnesia source or a silica source, or a fine aluminum titanate ceramic powder itself, preferably molded, to form a powder An aluminum titanate-based ceramic is produced by firing in the state or the state of a molded body.
