Claim 3:
4. The production process according to claim 1, wherein the polyethylene to be produced is the following polyethylene:
having a ratio (WLog 10M>5.25/RLS) of a weight fraction (WLog 10M>5.25: represented in wt %) of a component with Log10 M of more than 5.25 in an integral distribution curve of polyethylene evaluated by gel permeation chromatography, where M represents a molecular weight in terms of polyethylene, to
a light scattering area ratio (RLS) of 5.7 or more and 6.7 or less, the light scattering area ratio represented by the following formula 1:

RLS=LS/LS′  (formula 1)

wherein LS denotes a light scattering area of a solution prepared by dissolving 40 mg of the polyethylene into 20 mL of o-dichlorobenzene, and
LS′ denotes a light scattering area of a solution prepared by dissolving 40 mg of standard polystyrene with a number average molecular weight of 1000 into 20 mL of o-dichlorobenzene.
