PROBLEM TO BE SOLVED: To provide a condensation preventive cap of hardware for a wooden framework, enhancing adhesion with a wooden framework material, capable of effectively preventing condensation by minimizing heat conduction of the hardware in an airtight house, superior in an appearance, and capable of absorbing an error in construction. SOLUTION: This synthetic resin disk-shaped cap 18 is fitted to a nut 6 with a washer being the hardware for the wooden framework, and is fitted in a counter bore 17 formed on an outside surface of the wooden framework material. An elastic rib 19 abutting on an inner peripheral surface of the counter bore 17, is arranged in an outer peripheral part, and the counter bore 17 is sealed by allowing the outer peripheral part of this elastic rib 19 to abut on the inner peripheral surface of the counter bore 17.
