Provided is a method of manufacturing a single crystal Si film. The method includes: preparing a Si substrate on which a first oxide layer is formed and an insulating substrate on which a second oxide layer is formed; forming a dividing layer at a predetermined depth from a surface of the Si substrate by implanting hydrogen ions from above the first oxide layer; bonding the insulating substrate to the Si substrate so that the first oxide layer contacts the second oxide layer; and forming a single crystal Si film having a predetermined thickness on the insulating substrate by cutting the dividing layer by irradiating a laser beam from above the insulating substrate. Therefore, a single crystal Si film having a predetermined thickness can be formed on an insulating substrate.
