Disclosed is a printing apparatus (110) that ejects a dispersion containing solid particles and a liquid. The printing apparatus (110) comprises a film (20) and an acoustic head (10). The film (20) comprises a first main surface (20a) and a second main surface (20b) which is the opposite side from the first main surface. The first main surface has a first concave (21) that stores a liquid (32) and a second concave (22) that is provided at the bottom face of the first concave (21) and stores solid particles (31). The acoustic head (10) focuses acoustic waves through the second main surface (20b) toward the first concave (21) and the second concave (22). According to the above constitution, even when a dispersion containing solid particles is ejected, the amount of solid particles contained in ejected droplets (33) can be rendered uniform and, thus, uniform printing can be realized.
