A channel for an aerosol stream passing from an inlet edge to an outlet edge is provided to a support member of an aroma cartridge. Moreover, a mixing space is provided at an inlet edge of the channels of the support member. The mixing space cancels non-uniformity of the flow amount and flow rate of the aerosol passing from the aroma-generating source to be heated to the support member, caused by the kind and the charged amount of the base member of the aroma-generating source to be heated, and allows a user to readily breathe the aroma components released from the aroma-generating source to be heated. The utilization of information in an ID chip realizes stabilization of the aerosol stream, stable support of the aroma-generating source to be heated when inserting a heating element, and improvement of easy operation when inserting the cartridge.
