A pattern forming apparatus (1) comprises an ejection part (41) for ejecting a patterning material to a main surface of a substrate (9) from a plurality of outlets. The ejection part (41) moves relative to the substrate (9) in a direction along the main surface of the substrate (9) by a stage moving mechanism (2) and a plurality of linear pattern elements are formed on the substrate (9). In forming the linear pattern elements, moving speed of the plurality of outlets relative to the substrate (9) is changed periodically by an outlets moving mechanism (44) and gnarl portions each of which spreads in a direction perpendicular to a direction extending the linear pattern elements (91) are formed in each linear pattern element (91). This makes it possible to form a pattern similar to parallel crosses on the substrate 9 appropriately while ejecting the patterning material from the plurality of outlets.
