PROBLEM TO BE SOLVED: To provide: a dispersion liquid containing a resin composition including PPE particles, which gives low dielectric constant and dielectric loss tangent which polyphenylene ether (PPE) originally has, and excellent heat resistance and adhesiveness; a prepreg manufactured by using the dispersion liquid; and a printed wiring board manufactured from the prepreg.SOLUTION: In a dispersion liquid containing a resin composition including PPE particles and a solvent, (1) PPE particles have such a size that the major axis is ≤30 μm, (2) ≥60% of the total particle number of the PPE particles has such a size that the major axis is ≥3 μm and ≤20 μm, (3) the PPE particles include ≥70 mass% PPE, and (4) the number average molecular weight of PPE included in the PPE particles is 8,000-40,000. |
