This paper deals with a few methods of design and experimental results on the band elimination filters consisting of electro-mechanical vibrators.　The principle of design consists of replacing LC elements of a bridge T type or a lattice type of resistance arms by equivalant L_0C_0 elements of electro-mechanical vibrators.　These band eliminators consisting of electro-mechanical vibrators have some merits compared to usual ones consisting of the electrical LC elements, that is, the excellent skirt characteristics of rejection, fewer branch elements, the points of miniatuarization and etc.　As electro-mechanical vibrators mentioned above, such transducer resonators as piezo-ceramic discs or vibrators sealed with piezo-ceramics are used, of which the higher modes or the spurious modes are suppressed by skillful arangements of their electrodes.　The design theory of these filters are discussed in detail and proven experimentally.　These filters wlli be put to practical use more and more.
