1. A method of manufacturing a negative electrode, the method comprising:

  • a first step of forming a plurality of columnar active material blocks capable of electrochemically storing and releasing lithium ions on a surface of a current collector;

    a second step of producing particulate lithium by vapor deposition; and

    a third step of disposing the particulate lithium produced in the second step in gaps between the active material blocks,wherein, in the third step, a liquid dispersion in which the particulate lithium is dispersed in a dispersing medium is applied to the current collector having the active material blocks, and the applied liquid dispersion is dried.
