Conductive dispersion and production method therefor

A method for producing a conductive dispersion including a conductive carbon material, a liquid component, and a resin component dissolved in the liquid component, in which

• the resin component includes a first component and a second component,
• the conductive carbon material is in a fibrous form or in an aggregate form, and
• a weight-average molecular weight Mw1 of the first component and a weight-average molecular weight Mw2 of the second component satisfy Mw1<Mw2,
• the method comprising:
• (i) a step of dispersing the conductive carbon material and a part of the resin component in the liquid component, to obtain an intermediate dispersion, and
• (ii) a step of dispersing a remainder of the resin component in the intermediate dispersion, wherein
• the part of the resin component used in the step (i) contains the first component more than the second component, and
• the remainder of the resin component used in the step (ii) contains the second component more than the first component.
