摘要: Provided is a double-walled container (1) including: an outer layer body (10); an inner layer body (20), which is provided in a pinched-off portion and which passes through the outer layer body (10). The pinched-off portion is formed in a bottom due to pinch-off using a splittable mold in blow molding. The bottom is provided, on an inner side in a radial direction of an outer edge portion (11a) thereof, which serves as a ground-contacting surface, with a substantially cross-shaped recess (11b), which is concave toward a mouth. The recess (11b) is configured by a first-direction recess portion (17a), which extends along an extending direction of the slit (14), and a second-direction recess portion (17b), which intersects with the first-direction recess portion (17a). The slit (14) is provided in a region in which the first-direction recess portion (17a) and the second-direction recess portion (17b) intersect with each other.
