A tamper resistance wall structure on a circuit board includes a wall body formed of a laminated board, and a tamper detection wiring provided in the wall body. An outer through hole is provided in an outer surface of the wall body, which is a side surface away from a protective area on the circuit board, and is formed perpendicular to a longitudinal direction of the outer surface and perpendicular to the circuit board. An inner through hole is provided in an inner surface of the wall body, which is a side surface close to the protective area on the circuit board, and is formed perpendicular to a longitudinal direction of the inner surface and perpendicular to the circuit board. A recess is formed on the inner surface, and the inner through hole is formed in the recess and is a part of the tamper detection wiring.
