    Abstract: Provided is a method for efficiently producing a levulinic acid ester from a cellulose-containing raw material or a carbohydrate-containing raw material in an alcohol solvent using an inexpensive, easily available catalytic system. In a method for producing a levulinic acid ester by reacting at least one of a cellulose-containing raw material and a carbohydrate-containing raw material in the presence of an alcohol and a catalyst, use is made of, as a catalyst, a combination of: at least one metal compound (exclusive of gallium acetylacetonate and indium acetylacetonate) selected from the group consisting of hydroxide salts, sulfates, nitrates, carboxylates, alkoxides, acetylacetonates, and oxides of at least one metal selected from the group consisting of metals belonging to Group XIII and Group XIV of the Periodic Table; and an organic sulfonic acid.

    Abstract: Provided are a structure for which ink wettability/spreadability in the width direction of a line drawn on a substrate is limited and a high aspect ratio can be achieved, a manufacturing method for said structure, and a line pattern. The present invention provides a structure comprising: a droplet overlapping solidification layer obtained by droplets sloping and continuously overlapping each other in the direction of movement of a substrate and solidifying, a droplet flow solidified layer obtained by the droplets flowing on the droplet overlapping solidification layer and continuously being solidified without the droplets overlapping, and recesses formed at the boundary region between the droplet overlapping solidification layer and the droplet flow solidified layer.
