Heating assembly and electric heating smoking set

A heating tube comprising a tube body having a first end and a second end that is opposite to the first end, a heating part, and a conductive part comprising a first conductive part and a second conductive part, wherein:

• the first conductive part and the second conductive part are disposed on the tube body and are in electrical connection with the heating part;
• the first conductive part comprises a first electrode part and a first extension part;
• the first electrode part is closer to the first end than the first extension part;
• the first extension part extends from the first electrode part towards the second end;
• the second conductive part comprises a second electrode part and a second extension part;
• the second electrode part is closer to the first end than the second extension part;
• the first extension part extends from the first electrode part towards the second end and at least a part of the first extension part is in direct contact with the heating part;
• the second extension part extends from the second electrode part towards the second end;
• an average circumferential width of the first electrode part is larger than an average circumferential width of the first extension part;
• and
• an average circumferential width of the second electrode part is larger than an average circumferential width of the second extension part.
