A manufacturing method of an MR thin-film magnetic head with an MR film and lead conductors overlapping each other, includes a step of depositing a conductor layer on at least the magnetoresistive effect film, a step of forming a cap layer patterned on the deposited conductor layer, and a step of dry-etching the deposited conductor layer through a mask of the patterned cap layer using an Ar gas and an O2 gas, an O2 gas or a N2 gas so as to pattern the deposited conductor film to form the lead conductors.
