The present invention improves the feeling in use when a finger is hooked on a finger grip. This syringe is provided with a cylinder, a syringe needle, a finger grip, and a plunger rod. The finger gripis provided with a cylindrical portion and a pair of finger hook portions. The finger hook portion has an inclined curved surfaceand an end-side curved surface. The inclined curved surfaceis disposed on a side, of a side surface of the finger hook portion, connected to the cylinder. In the inclined curved surface, the inclination of a base-side region with respect to the center axis of the cylindrical portion is gentler than the inclination of an end-side region with respect to the center axis of the cylindrical portion. The end-side curved surfaceis disposed at the boundary between the end of the finger hook portion and the inclined curved surface. The end-side curved surfaceextends along the boundary.

A method for producing a microcapsule powder includes a concentration step. In the concentration step, an aqueous dispersion of a microcapsule is supplied into a cyclone, and the aqueous dispersion is then concentrated. The concentration step includes an aqueous dispersion-supplying step and a concentrated dispersion-recovering step. In the aqueous dispersion-supplying step, the aqueous dispersion is supplied into a cylindrical member inlet. In the concentrated dispersion-recovering step, a microcapsule dispersion is recovered. The microcapsule dispersion is discharged through a conical member outlet.
