Circuit board connecting structure

A circuit board connecting structure for connecting between a circuit board and various types of electrical components comprising:

• a case, comprising:
• an inner peripheral wall surrounding a space wherein the various types of electrical components are contained;
• and
• an electrode structural unit that comprises, as a substrate, an insulating material that is fitted into, and held removably in, a portion of the inner peripheral wall;
• wherein the electrode structural unit comprises:
• a plurality of through-electrodes provided extending through the inner peripheral wall of the case in a direction that is perpendicular to the circumferential direction thereof;
• wherein the through-electrodes comprise end faces on one side exposed on one side face of the insulating material as first electrode surfaces and have end faces on the other side exposed on the other side face of the insulating material as second electrode surfaces;
• wherein the circuit board is attached to the case so that the electrodes formed on the circuit board are in contact with the first electrode surfaces of the through-electrodes;
• and
• wherein the various types of electrical components are contained within the case so that the electrodes for connecting the various types of electrical components contacted the second electrode surfaces of the through-electrodes.
