To prevent an adhesive from flowing into nozzles, there is provided a head chip includes: a plate having a plurality of grooves; a cover plate having an introduction aperture; a nozzle plate fixed to an end surface of the plate, and has nozzles formed at the same intervals; and escape holes formed between the nozzle plate and the plate, each have a contour which surrounds a periphery of each of the nozzles with the contour being spaced apart from a contour of each of the nozzles by at least a given distance, accumulate the adhesive remaining at a time of fixing the nozzle plate therein, and allow the nozzles and the grooves to communicate with each other. The nozzles and the escape holes are so arranged as to be displaced from adjacent nozzles and adjacent escape holes by a given distance in a vertical direction of the nozzle plate.
