PROBLEM TO BE SOLVED: To increase the price competitiveness of a product because a silicon thin film used for a semiconductor, a solar battery, a secondary battery, etc. can be easily manufactured with a small number of processes and low cost as compared with conventional processes. A method for manufacturing a silicon thin film is provided. SOLUTION: A silicon oxide thin film is formed by applying and sintering silicon oxide on a substrate, and this is electrochemically reduced to form a porous silicon film, and then rebaked. The present invention relates to a method for manufacturing a silicon thin film including a step of bonding, a silicon thin film manufactured thereby, and an electronic device including the silicon thin film.
