A ceramic multilayer substrate excellent in migration resistance and having high bonding strength between the resin sealing material and the ceramic multilayer substrate main body and a method for producing the same are obtained. The entire laminated substrate body (2) is covered with a siloxane film formed by the PVD method, including the lands (16), (17) and the external electrodes (24), (25). The thickness of the siloxane film is set to less than 100 nm. Thereafter, the external electrodes (13) and (14) of the mounting component (11) are electrically connected to the lands (16) and (17) of the multilayer substrate main body (2) by the solder (19) and firmly Fix it. Next, a resin sealing material (4) for sealing the mounting component (11) is formed on the multilayer substrate body (2). |
