Abstract: A polylactic acid resin composition contains a polyactic acid resin satisfying: (1) the polylactic acid resin has a melt viscosity of 2,000 to 40,000 Pa·s at 190 degrees C.; and (2) the polylactic acid resin has a region of a weight average molecular weight Mw of 1,000 or less of 10 or less percent and a region of a weight average molecular weight Mw of 500,000 or more of 20 or more percent in a region of a weight average molecular weight Mw of 100 or more of a molecular weight distribution as measured by gel permeation chromatography, wherein the polylactic acid resin accounts for 90 or more percent of the polylactic acid resin composition.

Abstract: According to one embodiment, an electronic device includes a wall and a substrate. The substrate is provided with an opening. The substrate includes an organic compound layer, a first surface of the organic compound layer, a second surface of the organic compound layer opposite the first surface, first wiring on the second surface, second wiring on the second surface, a first pad, and a second pad. The first surface is attached to the wall. The first pad is connected to the first wiring. The second pad is connected to the second wiring away from the first pad. The opening penetrates the organic compound layer to open to the first surface and the second surface between the first pad and the second pad.

Abstract: The present invention provides carbon nanotubes perpendicularly and densely deposited over a wide area of a substrate. The carbon nanotubes are manufactured by supplying alternating-current power at a specific frequency between an anode and a cathode disposed in a reactor, and causing plasma to be generated between the anode and the cathode by introducing mixed gas containing an aliphatic hydrocarbon having 1-5 carbon atoms and hydrogen or mixed gas containing an aromatic hydrocarbon and hydrogen. The substrate is disposed between the anode and the cathode and held at a distance two times or less of the mean free path of a hydrocarbon cation from the anode.
