Abstract
In a technology for manufacturing a battery electrode by applying an application liquid containing an active material, stripe-shaped pattern elements are formed at narrower intervals than before while contact between the pattern elements is avoided. While a nozzle 21 including a multitude of discharge openings in an X-direction is moved to scan in a Y-direction relative to a base material 110, an application liquid containing an active material is discharged from the respective discharge openings and applied to the base material 110. Between pattern elements 221 formed by a first scanning movement, pattern elements 222 are formed by applying the application liquid anew by a second scanning movement. By making the start positions of the pattern elements 221, 222 different in a scanning direction (Y-direction), contact between the pattern elements resulting from the spread of the application liquid at pattern element start ends is prevented.
