A busbar of the present invention increases yield per metal material in comparison to plate-shaped bus bars, enables provision of protrusions on a member located inside relative to a conductor, and enables formation of the busbar in a bent shape. The busbar of the present invention is provided with a busbar insulator (22), a busbar conductor (23), a busbar insulator (24), a busbar conductor (25), and a busbar insulator (26) formed outside of a busbar center conductor (21). These conductors and insulators are arranged alternately from the inner side towards the outer side in a radial direction (R) that intersects at right angles with the axial direction (A) of the bus bar. The busbar conductors (23, 25) are provided with openings (23o, 25o) along the whole length in the axial direction (A) thereof.

Sound absorbency is imparted on a panel, which has increased strength and rigidity, by laminating a foam resin that is not originally permeable and does not absorb sound, and surface sheets that are not originally permeable and do not absorb sound. A sound absorption panel 1, obtained by laminating a foam resin 20 comprising closed cells and aluminum alloy sheets 10 (metal sheets), has a plurality of holes 30 formed therein, which penetrate the foam resin 20 and the aluminum alloy sheets 10 in the thickness direction. The holes 30 are formed by forcing a needle 40 (hole-forming means) through the foam resin 20 and the aluminum alloy sheets 10.

Provided is a lightweight heat ray shield cover, such as a heat insulator, which has a three-dimensional shape and excellent shielding characteristics. The heat ray shield cover is a cover which is disposed near a heat source (26) such as an engine exhaust pipe and blocks the heat ray from the heat source, the cover being formed of a shaped composite in which aluminum alloy plates (2a, 2b) are layered on both the surfaces of a core foam resin (3b), respectively. The surface of one (2a) of the aluminum alloy plates in the shaped composite is provided to face the heat source (26).

The present invention is intended to provide compositions which exert excellent effects allowing improvement in the mental function of humans and animals other than humans, such as reduction of mental fatigue, maintenance and enhancement of concentration maintenance and enhancement of mental vigor, and the like. These compositions are provided as mentally functional compositions containing, as the active component, a mixture component comprising caffeine, theanine, and arginine which are contained in tea. It is preferable that caffeine, theanine, and arginine are mixed such that the mixing ratio approaches a ratio of 1:2:2. Further, by combining the above-described mixture component with sugar and citric acid, mentally functional foods and beverages can be also provided which are taken with ease and effective.
