  "textContent": "A secondary battery that includes a positive electrode, a negative electrode, and an electrolytic solution. The positive electrode includes a positive electrode active material and a plurality of fibrous materials. The fibrous materials are tangled with each other and form a three-dimensional mesh structure. The fibrous materials each include a carbon fiber part, and a plurality of carbon covering parts that cover a surface of the carbon fiber part and hold the positive electrode active material. The carbon covering parts are spaced from each other in an extending direction of the carbon fiber part. The carbon fiber part includes a plurality of exposed parts that are not covered with the carbon covering parts. The fibrous materials have a flexibility F that is higher than or equal to 8.6 and lower than or equal to 19.2.",
