Provided are a glass body for pressure forming enabling press forming in a low-temperature range without the need of a special mold material, and a method for manufacturing the same. A glass body for pressure forming 1 having a porosified layer 1b formed by porosifying a surface thereof and having a Vickers hardness of 85 N/mm2 or less on the porosified surface. The porosified layer 1b can be manufactured by phase-separating the glass body by spinodal decomposition, acid-treating the phase-separated glass body and then treating the acid-treated glass body with alkali or hot water to porosify the surface of the glass body.
