PROBLEM TO BE SOLVED: To improve reliability by preventing peel-off of an adhesive. SOLUTION: A liquid injection head comprises: a flow path forming substrate 10 in which a plurality of pressure generating chambers 12 communicating with nozzle openings 21 to inject a liquid, and a communicating section 13 communicating with the pressure generating chambers12 are formed; pressure generating means 300 which is provided in the flow path forming substrate 10 and generates pressure change in the pressure generating chambers 12; and a reservoir forming substrate 30 comprising the reservoir section 31 which is bonded to one side surface of the flow path forming substrate 10 via an adhesive 35, communicates with the communicating section 13, and comprises part of a common liquid chamber 100 for the pressure generating chambers 12. The liquid injection head also comprises an adhesive layer 200 consisting of metal or metal oxide at least around the reservoir 31 in the bonding area bonded to the flow path forming substrate 10, in the reservoir forming substrate 30.
