A slurry containing carbon black and capable of contributing to a reduction in internal resistance of a secondary battery is provided. A slurry containing at least carbon black and a dispersion medium, wherein the carbon black concentration in the slurry is 5 mass % or more and 25 mass % or less, and in the frequency distribution of the volume-based particle size of carbon black measured by laser diffraction/scattering method, , the volume concentration of carbon black with a particle diameter of 0.6 μm or more is x (%), the volume concentration of carbon black with a particle diameter of 0.3 μm or more and less than 0.6 μm is y (%), and the volume concentration of carbon black with a particle diameter of less than 0.3 μm is 100-(x) +y) (%), a slurry in which 10≤x≤70, 30≤y≤90, and 0≤100-(x+y)≤30. |
