PROBLEM TO BE SOLVED: To provide a droplet coating device capable of correctly controlling a pressing pressure of a needle for coating with respect to a base material with a simple configuration.SOLUTION: A droplet coating device includes: a base material support part for supporting a base material; a coating liquid storage part which is arranged so as to face the base material supported by the base material support part, in which a coating liquid is stored and in which a micropore is formed having the size from which the coating liquid does not flow out on a bottom surface; a needle for coating which is arranged in a position above the micropore of the coating liquid storage part, and which can move between a state where the coating liquid is attached to a tip, and a state where the micropore is penetrated; and a needle for coating driving part for moving the needle for coating so as to bring the coating liquid attached to the tip of the needle for coating into contact as droplets with respect to the base material on the base material support part. The needle for coating is made of alloy having superelasticity, and the needle for coating driving part moves the needle for coating so as to bring the tip of the needle for coating into contact with respect to the base material on the base material support part. 【課題】簡易な構成により、基材に対する塗布用針の押付け圧力を正確にコントロールすることができる液滴塗布装置を提供する。【解決手段】基材の支持する基材支持部と、基材支持部に支持された基材に対向するように配置され、内部に塗布液が収容されると共に、底面に塗布液が流出しない大きさの微小孔が形成されている塗布液収容部と、塗布液収容部の微小孔に対する上方位置に配置されて先端に塗布液が付着された状態と当該微小孔を貫通した状態との間で移動可能である塗布用針と、基材支持部上の基材に対して塗布用針の先端に付着されていた塗布液を液滴として接触させるように塗布用針を移動させる塗布用針駆動部と、を備え、塗布用針は、超弾性を有する合金からなり、塗布用針駆動部は、基材支持部上の基材に対して塗布用針の先端を当接させるように当該塗布用針を移動させることを特徴とする液滴塗布装置である。【選択図】図１
