Providing a dispersion liquid excellent in mixability with varnish, coatability, dispersibility and dispersion stability, and a method for producing a metal plate and a printed circuit board A dispersion in which the powder is dispersed in an organic solvent containing an organic solvent and a powder, wherein the powder contains a tetrafluoroethylene polymer having a melt viscosity of 1 × 10 2 to 1 × 10 6 Pa·s at 380°C. A dispersion liquid having a thixotropy ratio of 1.0 to 2.2 calculated by dividing the viscosity measured under a condition of a viscosity of 50 to 10000 mPa·s and a rotation speed of 30 rpm by a viscosity measured at a rotation speed of 60 rpm. |
