Abstract
A bypass type prefilled syringe has a tubular body formed with a bypass for establishing communication between front and rear compartments for preliminarily storing medicament and pharmaceutical liquid, respectively. A gasket for dividing interior space of the tubular body into the front and rear compartments includes a plurality of circumferential ribs . A plurality of annular recesses are each formed between neighboring ones of the circumferential ribs. First and second axial slots are formed on the circumferential ribs so as to define a bent outflow path for the pharmaceutical liquid at the time of communication between the front and rear compartments via the bypass.
