Abstract

In order to provide a paste dispenser capable of determining a relative position between a syringe and an attachment member at a predetermined position, a paste dispenser includes an attachment member (M) that is detachably attached to a syringe (3) including discharge ports (51, 51'). The attachment member (M) includes a tubular external body (OM), into which the syringe (3) is inserted and which is rotatable about a central axis (CA), and an inside member (IM) that is disposed inside the external body (OM). The external body (OM) is fixed to the syringe (3) via an engagement structure configured to engage by insertion of the syringe (3) along the central axis (CA) and by rotation of the external body about the central axis (CA). The engagement structure includes at least three engagement pairs, each pair including an engaging portion (45) that is formed on the syringe (3) and an engaged portion (107) that is formed in the external body (OM) and engageable with the engaging portion (45). The at least three engagement pairs are aligned along a rotation direction of the external body (OM) and are non-point symmetrical about a central point on the central axis (CA) when viewed along the central axis (CA).
