A turbocharger, comprising: a scroll part for introducing exhaust gas into a nozzle flow passage of a turbine disposed in an exhaust passage of a engine, wherein the scroll part includes at least two scroll passages including a first scroll passage (Pa) and a second scroll passage (Pb), and is configured such that a first range (Ra) of the nozzle flow passage into which the exhaust gas flowing through the first scroll passage (Pa) is introduced does not overlap with a second range (Rb) of the nozzle flow passage into which the exhaust gas flowing through the second scroll passage (Pb) is introduced, in a circumferential direction of the nozzle flow passage, wherein the first scroll passage (Pa) includes: a division wall disposed along a flow direction of the exhaust gas within a predetermined range in the first scroll passage (Pa), the division wall dividing the first scroll passage (Pa) into a radially outer side scroll passage and a radially inner side scroll passage positioned on a radially inner side of the radially outer side scroll passage, and having a communication hole which brings the radially outer side scroll passage and the radially inner side scroll passage into communication; a flow-rate control valve disposed on an upstream side of the division wall, wall, for adjusting a flow rate of the exhaust gas flowing through the radially outer side scroll passage and the radially inner side scroll passage; and wherein, when a portion downstream of a line connecting a center of a shaft of the turbine and a tip of a tongue of the first scroll passage (Pa) is a downstream portion (Pad) and a portion upstream of the downstream portion (Pad) is an upstream portion (Pau) in the first scroll passage (Pa), the flow-rate control valve is positioned in the upstream portion (Pau), and wherein the division wall is formed over the downstream portion (Pad) and the upstream portion (Pau), and a tip portion on an upstream side of the division wall is disposed downstream of the flow-rate control valve. a scroll part for introducing exhaust gas into a nozzle flow passage of a turbine disposed in an exhaust passage of a engine, wherein the scroll part includes at least two scroll passages including a first scroll passage (Pa) and a second scroll passage (Pb), and is configured such that a first range (Ra) of the nozzle flow passage into which the exhaust gas flowing through the first scroll passage (Pa) is introduced does not overlap with a second range (Rb) of the nozzle flow passage into which the exhaust gas flowing through the second scroll passage (Pb) is introduced, in a circumferential direction of the nozzle flow passage, wherein the first scroll passage (Pa) includes: a division wall disposed along a flow direction of the exhaust gas within a predetermined range in the first scroll passage (Pa), the division wall dividing the first scroll passage (Pa) into a radially outer side scroll passage and a radially inner side scroll passage positioned on a radially inner side of the radially outer side scroll passage, and having a communication hole which brings the radially outer side scroll passage and the radially inner side scroll passage into communication;
