    Abstract: A rigid flexible printed circuit board (RFPCB) may include: a first base conductive layer; a first rigid conductive layer spaced apart from the first base conductive layer in a first direction; a second rigid conductive layer spaced apart from the first base conductive layer in the first direction and spaced apart from the first rigid conductive layer in a second direction intersecting the first direction; a base cover layer spaced apart from the first base conductive layer in the first direction and positioned closer to the first base conductive layer than to the first rigid conductive layer and the second rigid conductive layer; a transmission line positioned between the first base conductive layer and the base cover layer; and a dummy metal layer disposed on the base cover layer, positioned between the first rigid conductive layer and the second rigid conductive layer, and overlapping the transmission line in the first direction.

    Abstract: A wiring circuit board includes a metal supporting board; an insulating layer; and a conductive layer in this order in a thickness direction. The conductive layer includes a terminal portion, and a tail line portion extending from the terminal portion. The terminal portion has a via portion that penetrates the insulating layer in the thickness direction and is connected to the metal supporting board. The tail line portion has a base end portion that has a width different from a width of the terminal portion in a direction orthogonal to the extending direction of the tail line portion and that is connected with the terminal portion; and a second via portion that penetrates the insulating layer in the thickness direction and that is connected to the metal supporting board.

    Abstract: A circuit board includes an insulating substrate including a wiring conductor and a first resin substrate that is made of a resin different from the insulating substrate and is laminated on the insulating substrate. The first resin substrate has a plurality of internal conductors located from a surface thereof facing the insulating substrate to a surface on a side opposite to the insulating substrate. Each of the plurality of internal conductors includes a part that is inclined with respect to a perpendicular to the surface facing the insulating substrate. Intervals at which the plurality of internal conductors are located on the side opposite to the insulating substrate are narrower than intervals at which the plurality of internal conductors are located on an insulating substrate side.
