PROBLEM TO BE SOLVED: To provide a porous glass fiber molded body having a plurality of through-holes juxtaposed linearly in one direction which is suitable for applications such as a filter, and can be manufactured inexpensively by a simple method. SOLUTION: This porous glass fiber molded body is manufactured by piling up a plurality of glass fibers or glass fiber precursors, or their strands, juxtaposing in one direction, and heat-treating them as it is under pressure, or heat-treating them after press molding to fuse the glass fibers or the glass fiber precursors leaving a gap between them. The obtained glass fiber molded body has a plurality of straw-like through-holes without branching arranged in one direction, the opening diameter of which can be made 10μm or below.
