An electrode structural unit is fitted into, and held removably in, a portion of an inner peripheral wall of a case. The electrode structural unit has insulating material as a substrate, and is provided with a plurality of through-electrodes through that pass through the insulating material in the vertical direction. Bottom face electrode surfaces that are exposed on the bottom face of the electrode structural unit are brought into contact with electrodes for connecting to the various types of electrode components within the case. The top face electrode surfaces that are exposed on the top face of the electrode structural unit are caused to contact the electrodes that are formed on the circuit board. |
