Cellulose fiber-dispersing resin composite material, formed body, and composite member

A cellulose fiber-dispersing resin composite material, comprising a cellulose fiber dispersed in a resin,

• wherein a content of the cellulose fiber is 1% by mass or more and less than 70% by mass based on the mass of the cellulose fiber-dispersing resin composite material, and
• wherein LL and LN satisfy the following [Expression 1-2] and [Expression 3-3]:
• 1.1<(LL/LN)<1.4 [Expression 1-2]
• (LL/LN)<(LL×0.0005+0.95) [Expression 3-3]
• when a length weighted average fiber length of the cellulose fiber is taken as LL, and a number average fiber length of the cellulose fiber is taken as LN, measured under the following measurement condition:
• <Measurement Condition>
• LL and LN are determined for the dissolution residue obtained by immersing the cellulose fiber-dispersing resin composite material in a solvent capable of dissolving the resin in the composite material, in accordance with Pulps-Determination of fiber length by automated optical analysis specified by ISO 16065 2001,
• wherein the length weighted average fiber length of the cellulose fiber is 520 μm or more and 991 μm or less.
