Abstract

It is intended to suppress occurrence of a crack in a fixed portion of a tube with respect to a tank. A plurality of tubes (A toD) are fixed to a sidewall () in a state in which they penetrate through the sidewall () via respective ones of a plurality of through-holes () formed in the sidewall () in such a manner as to be arrayed in a line along a longitudinal direction. A heat exchanger () comprises a protective member () fixed to the sidewall () to protect a nearest tube (A) nearest to an end wall () among the plurality of tubes (A toD), wherein the protective member () has a barrier portion () interposed between the end wall () and an outlet-side end portion () of the nearest tube (A) disposed inside the sidewall ().
