An objective of the present invention is to provide a vibration-damping fiber-reinforced molded resin object having high mechanical characteristics and high vibration-damping. The fiber-reinforced molded resin object includes a polyimide fiber and a resin. The polyimide fiber has a fiber diameter in the range of 10.0 m or more and 18.0 m or less. The polyimide fiber in the fiber-reinforced molded resin object has a volume content in the range of 40% or more and 70% or less. The fiber-reinforced molded resin object has, when measured in an environment at 23 C., a damping loss factor of 0.005 or more at a natural frequency of 6400 Hz or less.
