1. A molded component that displays an optical image that is visible from a front by allowing light that is emitted from a light source that is disposed at a back to pass therethrough, the molded component comprising:
a light-shielding resin member that has an optical transmission hole that has a shape depending on the optical image in a plan view, the light-shielding resin member having a vertical support structure along a length of the light-shielding resin member; and
a transparent resin member that is optically transparent and that is stacked on a surface of the light-shielding resin member that faces the front such that the transparent resin member covers at least the optical transmission hole,
wherein the transparent resin member includes:
a peripheral portion that has a constant thickness; and
a thin portion that is disposed inside the peripheral portion and that is thinner than the peripheral portion,
the light-shielding resin member includes a domed projecting portion on the surface that faces the front such that a height of the domed projecting portion gradually increases from a peripheral portion of the light-shielding resin member toward a center portion of the light-shielding resin member,
a surface of the transparent resin member that faces the front is flat,
the transparent resin member includes a recessed portion that is in close contact with the domed projecting portion and that has a curved shape on a surface that faces the back, and
the recessed portion forms the thin portion such that a thickness of the recessed portion gradually decreases from the peripheral portion of the transparent resin member toward a center portion of the transparent resin member.
