A method for producing a molded body in which the matrix of a composite material is prevented from penetrating into carbon foam. The method includes: disposing a thermosetting adhesive (3) on a porous body (2), disposing a composite material (4) containing a thermosetting resin as a matrix on the adhesive, curing the adhesive, and liquefying and curing the matrix of the composite material after the adhesive has been cured. In this production method, because the cured adhesive bonds strongly to the porous body before the matrix of the composite material is liquefied, the subsequently liquefied matrix of the composite material can be prevented from penetrating into the interior of the porous body.
