BURNING TYPE HEAT SOURCE, FLAVOR INHALER, AND MANUFACTURING METHOD OF BURNING TYPE HEAT SOURCE |
| 摘要 |
A burning type heat source (50) has a single longitudinal hollow (51) extending along the first direction (D1). The longitudinal hollow (51) includes: a first hollow (51A) having a first cross section area; and a second hollow (51B) having a second cross section area smaller than the first cross section area. The first cross section area of the first hollow (51A) is 1.77 mm2 or more. |

1. A burning type heat source extending along a first direction from an ignition end toward a non-ignition end, the burning type heat source having a single longitudinal hollow extending along the first direction, wherein
the longitudinal hollow includes:
a first hollow having a first cross section area in a perpendicular cross section perpendicular to the first direction; anda second hollow located at a non-ignition end side relative to the first hollow, the second hollow having a second cross section area smaller than the first cross section area in the perpendicular cross section, and the first cross section area is 1.77 mm2 or more. |
