Abstract
An object of the present invention is to obtain a fiber-reinforced composite material achieving both lightweight properties and mechanical properties at a high level. The present invention provides a fiber-reinforced composite material including a resin (A) and a reinforcing fiber (B), and having: a porous structure portion having micropores with an average pore diameter of 500 μm or less as measured by a mercury intrusion method; and a coarse cavity portion defined by the porous structure portion and having a maximum length of more than 500 μm as a cross-sectional opening portion.
