Composite molded article

A composite molded article, comprising:

• a metal member using metal as a base material and having a surface;
• and
• a fiber-reinforced polymer material portion coated on at least part of the surface of the metal member and having a polymer material as a matrix and a plurality of reinforcing fibers for reinforcing the matrix;
• the surface of the metal member having a plurality of projections juxtaposed regularly or randomly at a pitch distance greater than diameters of the reinforcing fibers and the respective facing projections forming enterable spaces which part of the polymer material constituting the fiber-reinforced polymer material portion enters and at least part of the reinforcing fibers can enter,
• the pitch distance being within a range of 30 to 2000 μm, and the projections being connected with each other in a plan view taken in a perpendicular direction to the surface of the metal member,
• wherein in the plan view the enterable spaces have a quadrangular shape in accordance with the projections being connected with each other in the plan view taken in the perpendicular direction to the surface of the metal member.
