A laminate defining a high-frequency laminated component includes a ground electrode on a bottom surface of a lowermost insulating layer. In an objective lens of the present invention, a first region that focuses laser beams of a BD, DVD, and CD standards, a second region that focuses the laser beams of the DVD and CD standards, and a third region that focuses the laser beams of the BD and the DVD standards are provided in this order from a center portion of the objective lens. Flexible and modular interface adapters are used to allow component designers to efficiently provide interoperable components without having to adhere to a strict datapath interface specification. Provision is made of a second chain containing series-connected MOS transistors, complementary to the first MOS transistors.
