Non-combustion type flavor inhaler, flavor source unit, and method for manufacturing member used in a non-combustion type flavor inhaler

A flavor source unit comprising:

• a flavor source;
• and
• a unit body connectable to an inhaler body included in a non-combustion type flavor inhaler, the unit body storing the flavor source, wherein
• in a state where the unit body is stored in the inhaler body, at least a part of an aerosol flow passage that guide aerosol generated by an atomization unit to a mouthpiece side is formed, the atomization unit atomizing an aerosol source without combustion,
• the aerosol flow passage includes:
• a first flow passage which guides an aerosol to the mouthpiece side through the flavor source;
• and
• a second flow passage which is different from the first flow passage, and
• an aerosol reduction rate of the second flow passage is smaller than an aerosol reduction rate of the first flow passage.

A method for manufacturing a member used in a non-combustion type flavor inhaler, comprising:

• a step A of manufacturing an aerosol flow passage forming member that forms at least a part of aerosol flow passage, the aerosol flow passage guiding aerosol generated by an atomization unit to a mouthpiece side, wherein
• the aerosol flow passage include:
• a first flow passage which guides aerosol to the mouthpiece side through a flavor source;
• and
• a second flow passage which is different from the first flow passage,
• an aerosol reduction rate of the second flow passage is smaller than an aerosol reduction rate of the first flow passage, and
• the step A includes a step of determining shapes of the first flow passage and the second flow passage so that an airflow resistance generated in the second flow passage when a gas distributed to the second flow passage passes through the second flow passage is equal to an airflow resistance generated in the first flow passage when a gas distributed to the first flow passage passes through the first flow passage.
