Abstract: A coating die includes a manifold, a supply port, a discharge port, a supply passage, and a discharge passage. The manifold, the discharge passage, and the discharge port are longer in a first direction, and an outline of the manifold viewed from a second direction includes a first outline part to which the discharge passage is connected and also includes a second outline part located opposite the first outline part. The second outline part includes a first taper part tilted to be closer to the first outline part toward an end of the manifold. When the dimension in the first direction from a connection part at which the supply passage is connected in the manifold to the end is set to 1, dimension ratio of the first taper part in the first direction is 0.4 or less.

Abstract: An offset fin for use in a heat exchanger includes a first corrugation structure and a second corrugation structure. The first corrugation structure includes a plurality of first fins aligned in a first direction. The second corrugation structure includes a plurality of second fins aligned in the first direction. The second corrugation structure is disposed in a second direction orthogonal to the first direction, with respect to the first corrugation structure. The first fins and the second fins protrude alternately in a third direction orthogonal to both the first direction and the second direction, and each have a protruding shape cross-section. In the first direction, the second fins are disposed offset from the first fins. Each of the first fins includes a first side wall inclined with respect to the second direction, and each of the second fins includes a second side wall inclined with respect to the second direction, at a side opposite to a side at which the first side wall is inclined.
