Zusammenfassung:To provide a bottle-type can exhibiting excellent sealing performance and cap opening performance. A vertex section 8a includes: a vertex end 8b which is a top end of a mouth neck section 4; an outer diameter maximum section 8c which is below the vertex end 8b and at which the outer diameter reaches a maximum; a winding section 8d which continues downward from the outer diameter maximum section 8c, and in which the outer diameter gradually decreases; and an outer peripheral wall section 8e which is connected below from the winding section 8d. The vertex end 8b, the outer diameter maximum section 8c, and the winding section 8d constitute smooth curved surfaces. The curvature in a cross-section of the outer peripheral wall section 8e cut in a plane including a center axis line Lc of the mouth neck section 4 is "0" or "negative" when the curvature of the winding section 8d is "positive". An inflection section 8f is formed between the winding section 8d and the outer peripheral wall section 8e. In the outer perip
