Abstract: A refrigerant heat exchanger has the passage defining member. The passage defining member is made of carbon fiber reinforced plastics. The passage defining member has a tube portion defining a refrigerant passage. The passage defining member has the plate portion which spreads from the tube portion. In the tube portion, carbon fibers are oriented to surround the tube portion. This orientation contributes to a pressure resisting performance in a radial direction of the tube portion. In the plate portion, the carbon fibers are oriented to protrude from the tube portion. This orientation contributes to improve mechanical strength in the plate portion. The carbon fibers are extended over both the tube portion and the plate portion. This orientation promotes thermal transfer over the tube portion and the plate portion.
