PROBLEM TO BE SOLVED: To provide an inexpensive method for forming a hole pattern in which an organic or inorganic viscous material can be applied efficiently and continuously, and a thick coating film of a stable shape with reduced bleeding, bubbles, and contamination is obtained by a simple process and non-contact application when the viscous material is applied on the surface of a base material and an electronic part high in reliability and good in production yield. SOLUTION: In the method for forming the hole pattern by applying the viscous material on the surface of the base material, while a discharge speed of the material from a nozzle is adjusted by changing gas pressure applied to the material, the material is applied non-contactwise in the X direction and the Y direction with a space formed between them. In the electronic part, the base material in which the pattern is formed on the surface by the method is used.
