摘要:
A pressure sensor is manufactured by forming a reflection movable diaphragm unit (2) on a silicon substrate (3) having a groove (26), forming an adhesive layer also serving as a spacer (24) around the unit, bonding the spacer (24) to a half mirror layer (11) of an optical fiber (1), and providing a diaphragm section (25) semicircular in cross section to the diaphragm unit (2).
