Abstract
A base substrate includes an insulator board comprising through holes penetrating between two opposed principal surfaces, penetrating electrodes provided within the through holes, and intermediate layers sandwiched between inner surfaces of the through holes and the penetrating electrodes and having surfaces with smaller concavities and convexities than those of the inner surfaces at the penetrating electrode sides.
