Preparation process of electrode for battery, comprising first application step for forming first linear part by relatively moving first nozzle which discharges first active material linearly with respect to current collector to form a plural of first linear parts on current collector, first drying step for drying first linear parts, second application step for forming second linear part between first linear parts by relatively moving second nozzle which discharges second active material with respect to current collector, and second drying step for drying first linear part and second linear part, wherein height H1 of first linear part and height H2 of second linear part satisfies the relational inequality (1): H1<H2. The active material layer has high aspect ratio, and gives lithium ion secondary battery excellent in high charge-discharge performance. |
