本发明涉及一种发泡成形体。抑制气球形状的气泡的产生。本公开的一方式的发泡成形体的特征在于,在沿发泡成形体的厚度方向(T)二等分时,发泡成形体的内表面侧(A)的厚度方向(T)上的平均气泡直径α1是发泡成形体的外表面侧(B)的厚度方向(T)上的平均气泡直径β1的1.2倍以上((α1/β1)=1.2),发泡成形体的内表面的表面粗糙度Sm是1000μm以上。
Generation of a balloon-shaped air bubble is suppressed. A foam molded article according to a mode of the present disclosure is characterized in that in a situation of being divided into two equal parts in the thickness direction T of the foam molded article, the average cell diameter ±1 in the thickness direction T on the inner surface side A of the foam molded article is 1.2 times ((±1/²1)=1.2) or greater of the average cell diameter ²1 in the thickness direction T on the outer surface side B of the foam molded article and that the surface roughness Sm of the inner surface of the foam molded article is 1000 µm or greater.
