To provide a resin product capable of sufficiently exhibiting a volatilization ability of a chemical evaporating at normal temperature for a long term compared to a conventional one.SOLUTION: A resin product 1 which includes a resin molding 2 having an opening ratio from a front side of 40-85% and containing 10-2,000 mg of a chemical evaporating at normal temperature, and a storage container 3 for storing the resin molding and having an opening and an air passage amount adjustment part 11 is such that: when a wind speed of air which passes the opening of the resin molding is 0.1-3 m/second, a volatilization amount of the volatile chemical from the resin molding is 0.01-0.5 mg per hour; and when an area of the opening of the storage container is maximum, and a speed of wind passing the opening of the resin molding is 0.1-3 m/second, a volatilization amount of the volatile chemical from the resin molding is 0.01-0.5 mg per hour.SELECTED DRAWING: Figure 1
