A liquid ejection device () comprising: a first tank () for retaining a liquid composition; a head () for ejecting the liquid composition; a first heater () for heating the liquid composition; a first channel (); a second heater () for heating the liquid composition passing through the first channel () at a heating temperature higher than that of the first heater (); a second channel (); a second pump (); and a first pump (), wherein the temperature difference between the heating temperature of the second heater () and the heating temperature of the first heater () is 65&#xb0; C. or less.

Liquid ejection device

Provided is a resin composite material having a small number of voids and excellent tenacity. The resin composite material may be one obtained by mixing a carbon material having a graphene structure and having a content of less than 1 weight % of a volatile component volatilizable at 200&#xb0; C. and a thermoplastic resin. The resin composite material may be a resin composite material including a carbon material having a graphene structure and a thermoplastic resin, the resin composite material containing 5 parts by weight or more of the carbon material per 100 parts by weight of the thermoplastic resin and having a breaking strain of 50% or more as measured according to JIS K 7161.
