## Abstract

An aerosol generating article includes: a tobacco element; and a pouch configured to wrap the tobacco element, and discharge, to the outside, an aerosol generated by the aerosol generating article being heated, wherein the pouch is impregnated with a moisturizer of about 10 parts by weight to about 30 parts by weight with respect to 100 parts by weight of the tobacco element.

## Claims

### Claim 1

An aerosol generating article comprising:
a tobacco element;
a pouch configured to wrap the tobacco element, and discharge, to the outside, an aerosol generated by the aerosol generating article being heated, and
a mouthpiece portion foldably coupled to the pouch, and configured to form a flow passage through which an aerosol generated by the aerosol generating article flows.

### Claim 2 (depends on 1)

The aerosol generating article of claim 1, wherein the pouch includes a porous material.

### Claim 3 (depends on 2)

The aerosol generating article of claim 2, wherein the porous material includes a cellulose material.

### Claim 4 (depends on 1)

The aerosol generating article of claim 1, wherein the pouch is impregnated with a moisturizer of about 10 parts by weight to about 30 parts by weight with respect to 100 parts by weight of the tobacco element.

### Claim 5 (depends on 1)

The aerosol generating article of claim 1, wherein the mouthpiece portion comprises:
an attachment segment attached to at least one region of the pouch; and
a mouthpiece segment foldably attached to the pouch, and being transformable in shape to form the flow passage.

### Claim 6 (depends on 5)

The aerosol generating article of claim 5, wherein the mouthpiece segment is foldable in a direction away from the attachment segment at a location where one end thereof is in contact with the attachment segment.

### Claim 7 (depends on 6)

The aerosol generating article of claim 6, wherein the mouthpiece segment is transformed while being unfolded, to form the flow passage through which the aerosol generated by the aerosol generating article flows.

### Claim 8 (depends on 7)

The aerosol generating article of claim 7, wherein the mouthpiece segment is rolled such that one end of the mouthpiece segment faces the other end facing the opposite direction to the one end.

### Claim 9 (depends on 7)

The aerosol generating article of claim 7, wherein the mouthpiece segment is transformed into a cylindrical or polygonal columnar shape.

### Claim 10 (depends on 5)

The aerosol generating article of claim 5, wherein the mouthpiece segment includes at least one opening through which air passes.

### Claim 11

An aerosol generating device for heating an aerosol generating article comprising a tobacco element, a pouch wrapping the tobacco element, and impregnated with a moisturizer, and a mouthpiece portion foldably coupled to the pouch and forming a flow passage through which an aerosol generated by the aerosol generating article flows, the aerosol generating device comprising:
an accommodation portion configured to accommodate at least one region of the aerosol generating article; and
a heater configured to heat the aerosol generating article accommodated in the accommodation portion.

### Claim 12 (depends on 11)

The aerosol generating device of claim 11, wherein a cross-sectional area of the accommodation portion is smaller than a cross-sectional area of the aerosol generating article, and the aerosol generating article is fitted into the accommodation portion.

### Claim 13 (depends on 12)

The aerosol generating device of claim 12, wherein the accommodation portion fixes the mouthpiece portion accommodated therein, coupled to the aerosol generating device.

### Claim 14 (depends on 11)

The aerosol generating device of claim 11, wherein the accommodation portion has a cross-sectional area increasing from an open one end toward the other end arranged toward the inside of the aerosol generating device.
