PROBLEM TO BE SOLVED: To provide a foam molded body in which high rigidity can be obtained while attaining lightening in weight, and a method for producing the same.SOLUTION: Provided is a foam molded body where a solid component with a sea-island structure in which a dispersed phase of a stretched structure consisting of a crystalline resin (b) is provided in the continuous phase consisting of an amorphous resin (a), and bubbles are formed in the solid component. In the cross-section of the foam molded body, the dispersed phase of the elongated structure is located in the vicinity of the bubbles in a state of being elongated along the tangential line direction of the periphery of each bubble. In the foam molded body, in the cross-section, it is preferable that the dispersed phase with the elongated structure is present within the concentric line of the circular body with the radius 1.26 times that of the circular body provided that each bubble is defined as the circular body.SELECTED DRAWING: Figure 1 |
