PURPOSE:To improve mounting efficiency in a module and the mounting efficiency of a printed wiring board by forming a connecting terminal leading out signals even to a section different from a signal leading-out terminal section. CONSTITUTION:Connecting terminals 14, 16 are fitted to sections, to which signal leading-out terminals 3 are mounted, in a ceramic module, and both ceramic modules are connected by conductors such as flat cables on surfaces except surfaces, to which the signal leading-out terminals 3 are fitted, in two ceramic modules. Consequently, electronic parts, which cannot be loaded due to the shortage of the number of the signal leading-out terminals, are incorporated, thus obtaining the ceramic module having high mounting density. The ceramic module and another ceramic module need not be signal-connected on the printed wiring board side to which the ceramic modules are set up. Accordingly, the mounting efficiency of the printed wiring board side can be enhanced.
