Specifically, the number of the conductive structures 90 may be two, and the two conductive structures 90 may be disposed on the short edge 4112 of the heat generating surface 412 opposite to the side of the heat generating structure 40 in a one-to-one correspondence manner, so as to avoid obstructing the liquid guiding channel 380. In some embodiments, the conductive structure 90 may be a thimble, and it is understood that in other embodiments, the conductive structure 90 may not be limited to be a thimble, and may be other conductive elements, such as a conductive sheet, a conductive wire, or the like.
