A heat transfer apparatus with a zigzag passage is provided. The apparatus includes a pair of opposed plates 11, 12, a bent plate 21 having a wavy cross sectional shape for dividing the space between both plates into a plurality of side-by-side passages 20a, 20b, and a pair of cover members 13, 14, bonded to the bent plate 21, for forming connecting portions 20c, 20d between the side-by-side passages. One sidewall portion 23a of both sidewall portions 23a, 23b of the bent plate 21 is coupled to the cover member 13 on one end of a rectangular groove. The other sidewall portion 23b is coupled to the cover member 14 on the other end of the rectangular groove. Thus, a zigzag passage 20 is formed in which one side of the rectangular groove is folded to oppose the other side of the rectangular groove.
