    Abstract: A nozzle capable of removing a surplus liquid material, which is adhered to outer surfaces of the nozzle and which affects a discharge operation, without undergoing a special process, and a liquid material discharge device provided with the nozzle. The nozzle (1) includes a body (2) having a liquid inflow space, and a discharge tube (4) communicating with the liquid inflow space and extending downwards from the body (2). A liquid removing member (16) is disposed at a lower end of the body (2) in a state laterally surrounding the discharge tube (4), and the liquid removing member (16) includes a groove-like space (15) that is formed between adjacent to of plural surrounding surfaces (10), and that generates capillary force acting in a direction laterally away from the discharge tube (4).

    Abstract: Disclosed is a coating apparatus configured to properly detect a liquid surface of a coating liquid stored within a slit nozzle. The disclosed coating apparatus includes a slit nozzle, a moving mechanism, a storage portion illumination unit, and an imaging unit. The slit nozzle includes an elongated main body, a storage portion configured to store a coating liquid within the main body, and a slit-shaped ejecting port configured to eject the coating liquid fed from the storage portion through a slit-shaped flow path, wherein at least a part of each of a first wall and a second wall which face each other in the main body is formed of a transparent member. The moving mechanism is configured to move the slit nozzle with respect to a substrate. The storage portion illumination unit is configured to illuminate an inside of the storage portion through the transparent member of the first wall. The imaging unit is configured to image the inside of the storage portion through the transparent member of the second wall.
