A piezoelectric unit with built-in safety arrangement which is adapted to equipped with all kinds of piezoelectric lighter so as to provide a safety lock feature for the piezoelectric lighter. The piezoelectric unit includes a piezoelectric housing having a lower base body and an upper actuation chamber; an operating member having an axial receiving cavity provided therein and being slidably fitted in the actuation chamber of the piezoelectric housing in a vertically movable manner; a high voltage generating means which is arranged in the base body for generating striking sparks at an ignition tip thereof when the operating member disposed in the actuation chamber is pressed downwardly towards the base body; and a safety arrangement which is arranged in the operating member for normally locking a downward movement of the operating member unless a turner member is operated with the downward movement of the operating member.
