    Abstract: The present invention provides a CFRP molded object including CFRP layers that are laminated to each other, and a vibration-damping elastic layer disposed between the CFRP layers. The vibration-damping elastic layer includes viscoelastic resin regions that are arranged separately from each other along the x-axis direction, and a high-rigidity resin region including a high-rigidity resin is provided between the viscoelastic resin regions. In the CFRP molded object, the vibration-damping elastic layer including the viscoelastic resin regions and is disposed between the CFRP layers, whereby vibration-damping properties are improved. The viscoelastic resin regions and are arranged separately from each other along the longitudinal direction of the CFRP layers, and the high-rigidity resin region having comparatively higher rigidity is disposed between the viscoelastic resin regions, whereby flexural rigidity along the longitudinal direction of the CFRP layers is secured.
