A resin supply material used for press molding or vacuum-pressure molding of a fiber-reinforced resin, the resin supply material including a continuous porous material and a thermosetting resin, wherein an average pore cross-sectional area ratio P expressed by formula (I) is 1.1 or more:&#x2003;&#x2003;(I)

Resin supply material, preform, and method of producing fiber-reinforced resin

A resin supply material is used for molding a fiber-reinforced resin and includes a continuous porous material and a resin. The continuous porous material has a bending resistance Grt of 10 mN&#xb7;cm or more at 23&#xb0; C., and a bending resistance ratio Gr of 0.7 or less, the bending resistance ratio Gr being expressed by the formula:

A resin supply material used for press molding or vacuum-pressure molding of a fiber-reinforced resin includes a reinforcing fiber base material and a thermosetting resin, wherein a tensile rupture strain of the reinforcing fiber base material is 1% or more at temperature T, and/or a tensile strength of the reinforcing fiber base material is 0.5 MPa or more at the temperature T, wherein Temperature T is a temperature at which the viscosity of the thermosetting resin is minimum in heating of the thermosetting resin at a temperature elevation rate of 1.5&#xb0; C./minute from 40&#xb0; C.
