A ceramic multilayer substrate which has excellent migration resistance and high bonding strength between a resin sealing material and a ceramic multilayer substrate body, and its manufacturing method are obtained. n The entire laminated substrate body (2) including lands (16) and (17), and external electrodes (24) and (25) is covered with a siloxane film formed by means of a PVD process. The thickness of the siloxane film is set less than 100 nm. After that, external electrodes (16) and (17) of a mounting component (11) are electrically connected and firmly hold to the lands (16) and (17) of the laminated substrate body 2 via solder (19). Next, a resin sealing material (4) for sealing the mounting component (11) is formed on the laminated substrate body (2). |
