A trigger type fluid ejector (100) comprises a body (110) having a discharge flow channel (111) and a cylinder (112) disposed therebelow, it being arranged that a piston (140) in the cylinder (113) is slid by a trigger (130). The trigger (130) has its hooking portion (131) swingably held by the body (110) and holds, with respect to the body (110), the turn-in portion (132c) of an extension as an elastic portion (132) integrally extending from the swing portion (114) of the hooking portion (131) and positions the front end (132e) of the extension to allow it to contact the hooking portion (131). The body (110) defines an inner space (R) between a cover (120) attached thereto and the discharge flow channel (111), with a core element (150) inserted in the discharge flow channel (111) and inner space (R). The core element (150) is integrally provided with a tongue piece (153) serving as a discharge valve in the vicinity of the discharge port (111a) of the discharge flow channel (111), and with a tongue piece (154) serving as a suction valve disposed in the inner space (R).
