1. A die coater comprising:
a main body of a die block which includes a manifold and a slit that communicates with the manifold and discharges an coating liquid; and spacers each of which is arranged on each of both end parts in a width direction of the slit, and define a width of a flow channel of the coating liquid, wherein each of the spacers has, from a supply side toward a discharge side of the coating liquid of the slit, a first face which defines a flow channel having a fixed width, a second face which is continuously connected to the first face and defines a flow channel having a width wider than the fixed width, and a third face which is continuously connected to the second face and constitutes a tip face, and when each of the spacer is viewed in a plan, assuming that an intersection point of a virtual extended line of the first face and a virtual extended line of the third face is defined as a reference intersection point, an intersection point of the first face and the second face is defined as a first intersection point, and an intersection point of the second face and the third face is defined as a second intersection point, an area of a notch region which is surrounded by a straight line formed by connecting the first intersection point and the reference intersection point, a straight line formed by connecting the reference intersection point and the second intersection point, and a continuous line along the second face, is larger than an area of a virtual triangle formed by connecting the reference intersection point, the first intersection point and the second intersection point. |
