To avoid generation of a poor appearance and to remove a bad effect on heat resistance by stretching a resin smoothly even on the surface of a mold corresponding to irregularities of a body surface in a blow molding.

In a thin heat resistant bottle-type container made of a synthetic resin having a stretching ratio in the peripheral direction of, for example, 2.8 or less, a decompression absorbing panel (5) provided on the trunk of the container has at least one raised section (6), the width in the peripheral direction of which is longer at the lower part than at the upper part, or has a projecting contour line toward the bottom of the container.
