To provide a ceramics body causing no failure in bending operation, discharge operation or the like at the time of application to various products, and a method for manufacturing the ceramics body having these characteristics simply and certainly.

A plurality of sheets 21a-21d having a desired shape are laminated to obtain a laminate 22 which is, in turn, baked and integrated to manufacture the ceramics body. In this manufacturing method, a coating agent 12 is bonded to at least one sectional planes 23a-23d constituted of the end parts of the respective sheets 21a-21d of the laminate 22 in such a state that at least the grooves provided to the sectional planes 23a-23d are filled and the laminate 22 is then syntered and integrated.
