Summary:PURPOSE: A magnetic bead sensing array device of cross form which is useful as a magnetic biosensor is provided to measure output voltage of vertical direction and to manufacture magnetic biosensor of high density and high sensitivity. CONSTITUTION: A magnetic bead sensing array device of cross form comprises: a substrate(1); plural magnetic resistance devices(20) of cross form which is formed using thin film for detecting bio molecules; an electrode pad(26a, 26b, 26c) which is connected with plural magnetic devices and is formed on the substrate; a bio molecule fixing layer(33) for fixing bio molecules; a protection layer(30) formed on the upper portion of the magnetic resistance device and electrode pad; and a magnetic bead container layer(34) which surrounds the bio molecule fixing layer. The magnetic bead container layer is formed using photosensitive thin film.
