In a method and a device for sealing a ceramic package of a SAW (Surface Acoustic Wave) filter, when making a ceramic package of an environmentally sensitive SAW filter such as a SAW duplexer filter or a SAW filter, a first sealing is carried out between a ceramic main body and a metal case so as to protect the chip component, and then, a second sealing is carried out also between the metal case and the ceramic main body again, so that the shielding effect against external electromagnetic fields would be superior, and so that costs are reduced and so that a workability improvement can be realized, and so that the sealing can be made more secure. The first sealing is carried out on a step that is formed on the top of the ceramic main body to bond the metal case thereupon. The second sealing is carried out on the top of the ceramic main body to bond the metal case on the ceramic main body.
