PROBLEM TO BE SOLVED: To provide a method for manufacturing a fiber-reinforced plastic molded body utilizing a structural article for facilitating resin flow and resin feed as a reinforcing material without requiring discarding of the structural article, for example, a sheet-like or mat-like structural article. SOLUTION: The method for manufacturing the fiber-reinforced plastic molded body comprises the steps of arranging an article 2 to be impregnated comprising a sheet-like reinforcing fiber material on a base stand 1 of a mold for molding, laying down a resin spreading member 3 for spreading and flowing a liquid matrix resin 11 on the article to be impregnated, covering hermetically these article to be impregnated and resin spreading member on the mold for molding with a bag film 5, and pouring the liquid matrix resin into the bag film under vacuum. In this method, the resin spreading member consists of the reinforcing fiber material bound with a compatible resin having compatibility with the liquid matrix resin, and the shape is held for a definite time, and after the resin spreading member is sucked and integrated on the article to be impregnated during this time, the compatible resin becomes compatible with the matrix resin with time and is absorbed into the matrix resin.
