摘要： The present invention discloses an atomizer and an atomizing assembly, including an adsorption substrate, a heating member, and a lead. The adsorption substrate is configured to adsorb a liquid atomizable medium, the heating member includes a heating body and an electrode connected with the heating body, and the heating body is disposed on a sidewall of the adsorption substrate. The electrode is partially or completely embedded in the adsorption substrate, and the lead is electrically connected with a portion of the electrode that is located in the adsorption substrate. Since the electrode extending from the heating body is partially or completely embedded in the adsorption substrate, and one end of the lead is embedded in the adsorption substrate, the adsorption substrate wraps the electrode and part of the lead of the heating member; due to that the heating body is poor in strength and easy to be deformed, while the structural strength of the electrode is good, the electrode can be embedded in the porous ceramic, so that the heating body of the heating member is not prone to being deformed due to the pulling of the lead during the assembly process, thereby avoiding the problem of core overburning because of the separation of the heating member and the adsorption substrate.
