A method for component mounting which reduces the length of time that a component mounter called alternate mounting component mounter takes for mounting components is a method for component mounting used for a component mounter including plural mounting heads which alternately mount components onto a board. The method includes specifying, as a first mounting head, one of the plural mounting heads which moves a shortest distance to the board (S2), and mounting the components onto the board which is brought into the component mounter, the mounting starting from the first mounting head (S14).
