A curved panel part includes: a curved panel made of metal; and a reinforcement joined to the curved panel and made of a plurality of FRP layers including continuous fibers, in which each of the plurality of FRP layers has a single fiber direction, at least one layer out of the plurality of FRP layers has a fiber direction different from that of another layer, in the plurality of FRP layers, a proportion of layers having an angular difference in the fiber direction of 30° or more is 15% or more of all of the layers, and when calculating, by defining a maximum principal curvature direction of the curved panel as a 0° direction and a direction orthogonal to the 0° direction as a 90° direction, each of a 0° direction component and a 90° direction component regarding the fiber direction of each FRP layer of the reinforcement joined to the curved panel, by using a trigonometric function, an expression (1) is satisfied.
