A flavor inhaler comprising: a cylindrical holding member extending from an ignition end (E1) to a non-ignition end (E2); a combustion heat source provided at the ignition end (E1); a flavor source provided on the non-ignition end (E2) side with respect to the combustion heat source ; an inside holding member that is provided into the cylindrical holding member , and retains at least the flavor source ; and an introduction port that introduces air to the flavor source , wherein the inside holding member has a first side wall having a cylindrical shape to surround at least a part of the flavor source ; the cylindrical holding member has a second side wall having a cylindrical shape to surround the first side wall ; the second side wall has a through-hole that is fluidly coupled to external air; there are provided a first flow path and the second side wall , the first flow path connecting the through-hole and the introduction port each other and passing between the first side wall and the second side wall , the second flow path connecting the flavor source and a suction port to suck flavor generated at the flavor source ; a flow-path forming member is formed such that a length of a flavor source outer perimeter segment (L1) that is a section corresponding an outer perimeter of the flavor source , in the first flow path , is longer than a shortest length (L2) connecting the introduction port and a location where fluid flows into the flavor source outer perimeter segment (L1); and the through-hole is provided on the ignition end side (E1) from an end part of the non-ignition end (E2) side of the flavor source . a cylindrical holding member extending from an ignition end (E1) to a non-ignition end (E2); a combustion heat source provided at the ignition end (E1); a flavor source provided on the non-ignition end (E2) side with respect to the combustion heat source ; an inside holding member that is provided into the cylindrical holding member , and retains at least the flavor source ; and an introduction port that introduces air to the flavor source , wherein the inside holding member has a first side wall having a cylindrical shape to surround at least a part of the flavor source ; the cylindrical holding member has a second side wall having a cylindrical shape to surround the first side wall ; the second side wall has a through-hole that is fluidly coupled to external air; there are provided a first flow path and the second side wall , the first flow path connecting the through-hole and the introduction port each other and passing between the first side wall and the second side wall , the second flow path connecting the flavor source and a suction port to suck flavor generated at the flavor source ; a flow-path forming member is formed such that a length of a flavor source outer perimeter segment (L1) that is a section corresponding an outer perimeter of the flavor source , in the first flow path , is longer than a shortest length (L2) connecting the introduction port and a location where fluid flows into the flavor source outer perimeter segment (L1); and the through-hole is provided on the ignition end side (E1) from an end part of the non-ignition end (E2) side of the flavor source . <EOS>
