When neighboring ceramic substrates are split apart by linear snaps, through-holes and holes with floors, which are formed across the snaps, are also split apart. By splitting apart such a ceramic aggregate substrate along the snaps, it is possible to obtain numerous ceramic substrates, in end faces of which recess portions are formed. In comparison with a case of splitting apart such that throwaway substrates are formed at surroundings of ceramic substrates, a number of the ceramic substrates that are split apart from one ceramic aggregate substrate is larger. Therefore, it is possible to keep a unit cost for each of the ceramic substrates lower. |
