Abstract
A circuit board including resistors on one surface of a board or substrate having through hole conductors arranged in a lattice like fashion. At least one electrode is formed on a surface of the resistors, at least one electrode being formed by removing a portion of a surface of the board or substrate coaxially with the through hole conductors thereby forming substantially disk-shaped resistors.
