    Abstract: Provided are a ball-type speed reducer and a rotary table device that are capable of performing high-speed rotation and high-rigidity rotation and suitable for reduction in size and weight. An index table 10 includes a ball-type speed reducer 20 and a table 50 that is fixed to an upper surface of a worm wheel 30 of the ball-type speed reducer 20. When the worm gear 22 rotates as the input shaft 24 of the ball-type speed reducer 20 rotates, balls 36 made of a magnetic material move along a ball groove 26 having a spiral shape. The worm wheel 30 rotates as the balls 36 move, and the table 50 rotates. The balls 36 are attracted and held by the permanent magnet 34 on the worm wheel 30 side, so that a case for preventing the balls 36 from coming off the worm wheel 30 can be omitted, whereby the total size and weight can be reduced. Backlash is not required, so that high-speed rotation and high-rigidity rotation are possible.

    Abstract: First, a unilayer wiring board is fabricated, which has wiring layers formed in desired shapes on both sides of an insulating base member; and a metal bump formed on the wiring layer on one side of the insulating base member. Then, a desired number of unilayer boards are prepared and stacked up. On that case, the board disposed in the uppermost layer is prepared without having a metal bump. The boards are positioned and stacked up in such a manner that a metal bump of one of adjacent boards is connected to a corresponding wiring layer of the other board. Thereafter, resin is filled into gaps between the stacked boards, and insulating layers are formed on both sides of a multilayer board obtained through the above steps, in such a manner as to cover the entire surface except pad areas defined at predetermined positions on the wiring layers.
