Abstract
A nonwoven fabric includes a fiber including a first portion and a second portion connected to the first portion. A first fiber diameter of the first portion is smaller than a reference fiber diameter. A second fiber diameter of the second portion is equal to or greater than the reference fiber diameter. The reference fiber diameter is smaller than 1 μm. A ratio of a maximum fiber diameter of the second portion to a length of a linear line connecting both end portions of the second portion is from 1/10 to ⅓.

A nonwoven fabric comprising:
- a fiber including a first portion and a second portion connected to the first portion,
- wherein a first fiber diameter (D1) of the first portion is smaller than a reference fiber diameter (Dx),
- a second fiber diameter (D2) of the second portion is equal to or greater than the reference fiber diameter (Dx),
- the reference fiber diameter (Dx) is smaller than 1 μm, and
- a ratio (D2max/L2) of a maximum fiber diameter (D2max) of the second portion to a length (L2) of a linear line (S2) connecting both end portions of the second portion is from 1/10 to ⅓.
