PURPOSE: To connect excellently constitutive layers patterned finely and complicatedly by providing a method wherein a connection having a predetermined pattern is formed on one connecting face, a connecting material having adhesive function is formed into a film on one connecting face, the thin film layer is patterned in a shape nearly same as the connection, and two constitute layers are connected to each other through the thin film layer.
CONSTITUTION: A connecting material 34 having adhesive function is formed into a film on a connecting face of a first plate 32 and a resist 35 is formed into a film on the connecting material 34. An optical mask 36 having a predetermined pattern is laid thereon so as to expose the resist 35 with a patterning light, to develop it, and the resist 35 is patterned. The connecting material 34 is etched with solvents from the top of the resist 35 so as to pattern. The connecting material 34 is patterned in nearly the same shape as a peripheral part, which is the connection of the first plate 32, and a pattern of a support wall. The resist 35 is removed from the top of the patterned connecting material 34, a second plate 33 is laid on the first plate 32 on which the connecting material 34 having a predetermined pattern is formed, so as to form a printer head 31 by connecting them by means of heating, pressurizing, and irradiating with ultrasonic wave.
