Abstract

The present invention has an object of providing a method for manufacturing an optical isolator that can reduce misalignment of the direction of the light transmission axis of a polarizer. The present invention relates to a method for manufacturing an optical isolator including a Faraday element (2), a magnet (7) in which the Faraday element (2) is internally provided, a first polarizer (3) disposed on a light incidence side of the Faraday element (2), a second polarizer (4) disposed on a light exit side of the Faraday element (2), a first polarizer holder (5) housing the first polarizer (3), and a second polarizer holder (6) housing the second polarizer (4) and is characterized by including the steps of: placing a magnetic body (9) into the first polarizer holder (5) and attracting the first polarizer holder (5) and the magnet (7) by a magnetic force; and adjusting a direction of a light transmission axis of the first polarizer (3) by rotating the first polarizer holder (5) after the step of attracting the first polarizer holder (5) and the magnet (7) by the magnetic force.
