CIRCUIT BOARD DEVICE FOR INFORMATION APPARATUS, MULTILAYERED MODULE BOARD, AND NAVIGATOR

A multilayered module board (300) with mounted high-frequency electronic components such as a CPU and a graphic circuit is mounted on one face of a base board (200) with mounted low-frequency electronic components. The multilayered module board (300) is a squared multilayered board smaller than the base board (200). The electronic components are wired with an inner layer-wiring pattern. Connector terminals (310) are solder-jointed to four sides of the multilayered module board (300). [0002] The multilayered module board (300) is mounted to the base board (200) via the connector terminal (310).
