A flutter wind tunnel test model simulates a shape and vibration property of an aircraft part, for a flutter wind tunnel test of the aircraft part. The model at least partially has non-solid structure having branched clearances inside. A volume of a portion, other than the clearances, of the non-solid structure, per unit volume is defined by density. A method of producing a flutter wind tunnel test model simulating a shape and vibration property of an aircraft part, for a flutter wind tunnel test of the aircraft part, includes: shaping non-solid structure with a three-dimensional printer and composing at least a part of the flutter wind tunnel test model using the non-solid structure. The non-solid structure has branched clearances inside. A volume of a portion, other than the clearances, of the non-solid structure, per unit volume is defined by density.
