Slot-type spray nozzle

A slot-type spray nozzle comprising at least two nozzle blocks, two air shim plates, two partition shim plates, and one coating fluid shim plate, which are layered in this order from an outside and an entirety of which are fastened in a layer direction by fixing bolts, wherein

• a surface from which coating fluid is discharged is defined as a coating fluid discharge surface, and a direction perpendicular to a direction in which the coating fluid is discharged and the layer direction is defined as a width direction,
• a coating fluid manifold extending in the width direction and an air manifold extending in the width direction are provided,
• in an end portion of the coating fluid shim plate on a side of the coating fluid discharge surface, grooves serving as a plurality of coating fluid discharge ports are formed at pitches, and the coating fluid manifold and the plurality of coating fluid discharge ports communicate with each other,
• in an end portion of each of the two air shim plates on the side of the coating fluid discharge surface, grooves serving as a plurality of air discharge ports are formed at a pitch, and the air manifold and the plurality of air discharge ports communicate with each other,
• the coating fluid discharge surface has a region where the coating fluid discharge ports and the air discharge ports do not exist in the layer direction, and
• the fixing bolt fastens the slot-type spray nozzle at a position closer to the coating fluid discharge surface than the coating fluid manifold and the air manifold.
