Claim:
1. A medicine inhaler that supplies a particulate medicine into a body by an airflow, comprising: a first airflow forming section that forms a core airflow; a second airflow forming section that forms a clad airflow outside the core airflow, the clad airflow having higher flow velocity than the core airflow; a medicine supply section that supplies the medicine into the core airflow to disperse the medicine into the core airflow; and an introduction section that introduces the core airflow, in which the medicine is dispersed, and the clad airflow into the body, further comprising a blower section in a housing for housing the first airflow forming section and the second airflow forming section, wherein a compressed air discharged from the blower section flows through the first airflow forming section and the second airflow forming section to form the core airflow and the clad airflow, respectively; wherein: the second airflow forming section has a second airflow passageway communicating with the blower section, the first airflow forming section is a first airflow passageway formed inside the second airflow passageway, the first airflow passageway being arranged in the same direction as the second airflow passageway and having an airflow resistance section, an air that is blown from the blower section and that is introduced into one end of the first airflow passageway to pass through the first airflow passageway becomes the core airflow; an air that is blown from the blower section and that is introduced into one end of the second airflow passageway to pass through the second airflow passageway becomes the clad airflow; and the medicine inhaler further has a medicine supply pipe that penetrates through the second airflow passageway to supply the medicine into the first airflow passageway.
