An ejection head, the ejection head comprises: a pressing member that is fitted to a stem standing from a mouth tubular portion of a container body and that is formed with an introduction path to which a content medium is introduced; a nozzle tip that is fitted to a concavity formed on a side surface of the pressing member and that is formed with an ejection orifice for the content medium pumped from the introduction path; and an insert member that is located inside the nozzle tip and that forms a communication path allowing the introduction path formed in the pressing member to communicate with the ejection orifice formed in the nozzle tip, characterized in that the insert member includes: a concave portion having an opening formed in a rear end of the insert member that faces to the pressing member, thereby forming a filling space to be filled with the content medium introduced from the introduction path; at least one through hole formed on a circumferential wall constituting the concave portion; and a long groove that is formed on the circumferential wall and that extends from the at least one through hole to the nozzle tip, and the insert member has a front end facing to the nozzle tip, the front end having an outer circumferential edge formed as an annular inclined surface tapered toward a front end thereof, and the front end being formed with a bulging portion that protrudes forward of the inclined surface, the bulging portion being formed with a plurality of radial grooves and a cylindrical groove where the plurality of radial grooves joins, and at least one of the at least one through hole is located in a position that is circumferentially offset from any of the plurality of radial grooves. a pressing member that is fitted to a stem standing from a mouth tubular portion of a container body and that is formed with an introduction path to which a content medium is introduced; a nozzle tip that is fitted to a concavity formed on a side surface of the pressing member and that is formed with an ejection orifice for the content medium pumped from the introduction path; and an insert member that is located inside the nozzle tip and that forms a communication path allowing the introduction path formed in the pressing member to communicate with the ejection orifice formed in the nozzle tip, characterized in that the insert member includes: a concave portion having an opening formed in a rear end of the insert member that faces to the pressing member, thereby forming a filling space to be filled with the content medium introduced from the introduction path; at least one through hole formed on a circumferential wall constituting the concave portion; and a long groove that is formed on the circumferential wall and that extends from the at least one through hole to the nozzle tip, and the insert member has a front end facing to the nozzle tip, the front end having an outer circumferential edge formed as an annular inclined surface tapered toward a front end thereof, and the front end being formed with a bulging portion that protrudes forward of the inclined surface, the bulging portion being formed with a plurality of radial grooves and a cylindrical groove where the plurality of radial grooves joins, and at least one of the at least one through hole is located in a position that is circumferentially offset from any of the plurality of radial grooves.
