A labeled resin bottle containing a resin bottle and one or more labels placed thereon and fused therewith, wherein said resin bottle has a value of W/(V⅔) within a range from 0.1 to 0.5 m, wherein W is a base weight, and V is a fill-in volume, provided that when the value is 0.1 or larger and smaller than 0.3, the bottle has a major thick layer consisting of a polyolefinic resin having a stiffness of 5,000 kgf/cm2 or below, and wherein said label has a tensile elastic modulus of 5,000 to 30,000 kgf/cm2. The labeled resin bottle is capable of withstanding reduced bottle strength while thinning the resin bottle and reducing the amount of source resins used therefor.
