PROBLEM TO BE SOLVED: To provide a liquid spray head and a liquid spray apparatus that can improve strength against reaction force generated when operating an actuator unit and improve discharge characteristics in liquid.SOLUTION: The liquid spray head and the liquid spray apparatus comprise: a flow channel unit 20 having a pressure generation chamber 21 communicated with a nozzle opening 61; an actuator unit 30 having a piezoelectric actuator 31 and a stationary member 34 to which the piezoelectric actuator 31 is fixed; and a case head 50 with a housing 40. In the housing 40 is formed an uneven portion 43 for narrowing width near the pressure generation chamber 21 of the housing 40. The stationary member 34 has a first stationary portion 35 to which the piezoelectric actuator 31 is fixed and a second stationary portion 36 connected to the first stationary portion 35. In the actuator unit 30, the piezoelectric actuator 31 is contacted with a region opposing to the pressure generation chamber 21 of the flow channel unit 20 and the second stationary portion 36 of the stationary member 34 is adhered with an adhesive 80 to an upper face 43a of the uneven portion 43 of the housing 40. |
