Lithium Metal Secondary Battery

A lithium metal secondary battery comprising:

• a power generation element;
• and
• an electrolyte, wherein
• the power generation element includes a positive electrode and a negative electrode,
• the negative electrode includes a base material and raised portions,
• the base material is electrically conductive,
• the raised portions are electrically insulating,
• depressed portions are formed on a surface of the base material,
• the raised portions are provided on the surface of the base material,
• the raised portions protrude outwardly from the surface of the base material, and
• a relationship of the following expression is satisfied:
• 0.001≤d/h≤10
• where
• d represents a depth of the depressed portions,
• h represents a height of the raised portions, and
• the depth and the height are relative to the surface of the base material.
