A value of (a length from the mouthpiece end to the center of gravity)/(a total length defined by a length from the mouthpiece end to the distal end) is in a range of 0.20 to 0.45. ## Claims ### Claim 1 A flavor aspirator comprising: a housing including a mouthpiece end and a distal end, the housing extending from the mouthpiece end to the distal end; and a weight-concentrated part including a first part provided in a vicinity of the mouthpiece end and a second part provided in a vicinity of the distal end, and that has a weight accounting for at least approximately half of the total weight, the weight being a sum of a weight of the first part and a weight of the second part, wherein a value of (a length from the mouthpiece end to the center of gravity)/(a total length defined by a length from the mouthpiece end to the distal end) is in a range of 0.20 to 0.45, and wherein the flavor aspirator has a rod shape or a cylindrical shape. ### Claim 2 (depends on 1) The flavor aspirator according to claim 1, wherein the weight-concentrated part has a weight accounting for 45% or more of a total weight, wherein the weight is a sum of a weight of a part where a value of (a length from the mouthpiece end to the weight-concentrated part)/(the total length) falls within a range of 0 to 0.2 and a weight of a part where a value of (a length from the mouthpiece end to the weight-concentrated part)/(the total length) falls within a range of 0.9 to 1.0 and accounts for 45% of the total weight. ### Claim 3 (depends on 1) The flavor aspirator according to claim 1, wherein an absolute value of a moment when a point where a value of (a length from the mouthpiece end to the weight-concentrated part)/(the total length) of 0.3 is gripped is 15.5 gf·cm or less. ### Claim 4 (depends on 3) The flavor aspirator according to claim 3, wherein an absolute value of a moment when a point where a value of (a length from the mouthpiece end to the weight-concentrated part)/(the total length) of 0.3 is gripped is 14.5 gf·cm or less. ### Claim 5 (depends on 3) The flavor aspirator according to claim 3, wherein a value of (a length from the mouthpiece end to the center of gravity)/(the total length) is in a range of 0.25 to 0.44. ### Claim 6 (depends on 5) The flavor aspirator according to claim 5, wherein a value of (a length from the mouthpiece end to the center of gravity)/(the total length) is in a range of 0.3 to 0.44. ### Claim 7 (depends on 1) The flavor aspirator according to claim 1, wherein an absolute value of a moment when a point where a value of (a length from the mouthpiece end to the weight-concentrated part)/(a total length defined by a length from the mouthpiece end to the distal end) is 0.3 is gripped is 11.25 gf·cm or less. ### Claim 8 (depends on 1) The flavor aspirator according to claim 1, wherein the total weight is in a range of 10.4 g to 15.5 g or less. ### Claim 9 (depends on 1) The flavor aspirator according to claim 1, wherein the weight-concentrated part is at least partially made of a metal. ### Claim 10 (depends on 1) The flavor aspirator according to claim 1, wherein the weight-concentrated part has a weight-adjustment member. ### Claim 11 (depends on 1) The flavor aspirator according to claim 1, wherein when the flavor aspirator is divided by a plane including a central axis extending from the mouthpiece end to the distal end, one of the divided segments is 1.5 times larger than the other of the divided segments. ### Claim 12 A flavor aspirator, comprising: a housing including a mouthpiece end and a distal end, the housing extending from the mouthpiece end to the distal end; and a weight-concentrated part including a first part provided in a vicinity of the mouthpiece end and a second part provided in a vicinity of the distal end, wherein the weight-concentrated part has a weight accounting for at least approximately half of a total weight, wherein the weight of the weight-concentrated part being a sum of a weight of the first part and a weight of the second part, wherein the weight of the first part is heavier than the weight of the second part, and wherein the flavor aspirator has a rod shape or a columnar shape. ### Claim 13 (depends on 1) The flavor aspirator according to claim 1, wherein the flavor aspirator is non-combustion type. ### Claim 14 (depends on 1) The flavor aspirator according to claim 1, comprising: an aerosol source; a heat source that generates aerosol by heating a liquid supplied from the aerosol source; and a power supply for supplying electric power to the heat source. ### Claim 15 (depends on 1) The flavor aspirator according to claim 1, further comprising: a battery housed in the housing, wherein the battery constitutes a part of the second part of the weight-concentrated part. ### Claim 16 (depends on 12) The flavor aspirator according to claim 12, further comprising: a battery housed in the housing, wherein the battery constitutes a part of the second part of the weight-concentrated part. ### Claim 17 (depends on 1) The flavor aspirator according to claim 1, wherein the housing is made of resin. ### Claim 18 (depends on 12) The flavor aspirator according to claim 12, wherein the housing is made of resin.
