PROBLEM TO BE SOLVED: To provide a thermoplastic substrate which can draw a highly precise pattern on a drawing surface even using droplets of a conductive ink, and to provide a method of manufacturing the thermoplastic substrate. SOLUTION: A film S of photocatalyst ink is formed on a drawing region on the drawing surface 18a of a liquid wiring pattern to be drawn on the drawing surface 18a, the film S of the photocatalyst ink is irradiated with an ultraviolet ray L so that the drawing surface 18a of the drawing region of a portion abutting to the film S of the photocatalyst ink can be reformed from a liquid repellency to liquid affinity, and the drawing region is allowed to have liquid affinity. Then, in the drawing surface 18a, the drawing region on the drawing surface 18a becomes liquid affinity and a non-drawing region except the drawing region on the drawing surface 18a becomes liquid repellency. Thus, metal ink droplets jetted to the drawing region of the drawing surface 18a do not wetly expand to the outside from the drawing region having affinity for liquid, but remain in a region Z1 having affinity for liquid, and a highly precise wiring pattern can be formed.
