    • This invention provides a void-containing resin molded product, which comprises a crystalline polymer and has continuous voids in its interior in such a state that the longitudinal direction of the voids is aligned in a single direction. The void-containing resin molded product is characterized in that, in the void-containing resin molded product in its cross section orthogonal to the direction of alignment of the voids, regarding 10 of the voids which are shortest in distance from the center of the voids to the surface of the void-containing resin molded product, the distance h (i) from each center to the surface of the void-containing resin molded product is calculated, the arithmetical average value h (avg) in each of the distances h (i) satisfies a relationship of h (avg) > T/100, wherein T represents the arithmetical average value of the thicknesses in the cross section, and the 10 voids are selected from voids present within a region sandwiched between any desired single straight line parallel to the thickness-wise direction and another straight line parallel to the single straight line and distant by 20 × T, and the L/r ratio is not less than 10 wherein r represents the average length of the voids in the thickness-wise direction orthogonal to the direction of alignment of the voids, μm, and L represents the average length of the voids in the direction of alignment of the voids, μm.
    • 本发明提供了一种含空隙的树脂模制产品,其包含结晶聚合物,并且在空隙的纵向方向在单个方向上对准的状态下在其内部具有连续的空隙。 含空隙的树脂成型体的特征在于,在与空隙的排列方向正交的剖面的含空隙的树脂成型体中,关于与空隙的中心距离最短的10个空隙 对于含空隙的树脂成型体的表面,计算从含空隙的树脂成形体的各中心到表面的距离h(i),在每个距离h(av)中的算术平均值h(avg) i)满足h(avg)> T / 100的关系,其中T表示横截面中的厚度的算术平均值,并且10个空隙选自夹在任何期望的单直线平行 至平行方向,另一条直线与单条直线平行,距离为20×T,L / r比不小于10,其中r表示厚度中空隙的平均长度 与空隙对齐方向正交的方向,μm和L表示空隙的排列方向上的空隙的平均长度,μm。
