Zusammenfassung:	PROBLEM TO BE SOLVED: To make various physical properties, such as flexibility, be favorable or stable, and to make mechanical strength to be excellent.SOLUTION: A multilayer foamed body 10 is a multilayer foamed body obtained by foaming a multilayered laminate including plural resin layers. The multilayer foamed body includes: two or more foamed resin layers 11 including plural bubbles 12; and three or more control resin layers 21. The foamed resin layers 11 and the control resin layers 21 are alternately laminated so that the foamed resin layers 11 are arranged between the control resin layers 21. The foamed resin layers 21 include bubbles foamed so as to extend in a ZD direction.SELECTED DRAWING: Figure 1 【課題】柔軟性等の各種物性を良好又は安定にしつつ、機械強度を優れたものとする。【解決手段】多層発泡体１０は、複数の樹脂層を有する多層積層体を発泡してなる多層発泡体であって、複数の気泡１２を有する２以上の発泡樹脂層１１と、３以上の制御樹脂層２１とを備え、制御樹脂層２１の間に発泡樹脂層１１が配置されるように、発泡樹脂層１１と制御樹脂層２１が交互に積層されており、発泡樹脂層２１が、ＺＤ方向に延びるように発泡した気泡を有する。【選択図】図１
