Abstract: A connection device (10) includes a flexible substrate (200), a coaxial connector (300) overlapping with the flexible substrate (200), and a jig (400) fixing the flexible substrate (200) and the coaxial connector (300).

Abstract: Provided is an antenna device having a structure that suppresses deterioration in performance as a profile becomes lower. Four FM band antenna elements and two AM band antenna elements are arranged side by side on an antenna base. Further, a circuit board including synthesis circuits in one-to-one correspondence with the antenna elements, respectively, is arranged in an inner space of the antenna elements. In order that omnidirectionality may be exhibited in a horizontal plane, each of the antenna elements includes a helically wound linear conductor, and a planar conductor that is electrically connected to the linear conductor at a part substantially the farthest from a ground plane (antenna base).

Abstract: This invention provides a composite material useful for size reduction of electronic components and circuit boards mounted on electronic equipment and exhibiting a low magnetic loss (tan ?), and a manufacturing method thereof. The composite material contains an insulating material and particulates dispersed in this insulating material, the particulates being previously coated with an insulating material having substantially the same composition as that of the coating insulating material. The particulates consist of an organic or inorganic substance and preferably have a flat shape. The insulating material may be an insulating material commonly used in the field of electronic components. The composite material of the invention is preferably manufactured by a manufacturing method in which the particulates are previously coated with an insulating material and dispersed in an insulating material having substantially the same composition as that of the coating insulating material.
