PROBLEM TO BE SOLVED: To provide a conical package that is easily gripped and stably held even if dew clings to the surface of the package due to condensation, etc. SOLUTION: The conical package has a seal 12 on the large-diameter side of a conical peripheral wall 10, and is opened by tearing the seal 12 off along a perforation line 22 formed in the peripheral wall 10. A rough face 30 is formed in an area of the surface of the peripheral wall 10, on the vertex 11 side of the cone rather than on the perforation line 22 side. Thus, the rough face 30 improves a grip characteristic. This provides easy grip and stable holding of the conical package even where dew clings to the surface of the conical package.
