Abstract
PURPOSE:To reduce external size and manufacture cost by forming a space for ensuring the oscillation of a piezoelectric substrate in an armoring case by using a sublimation material. CONSTITUTION:A couple of lead terminals 21, while connected to the electrodes of a piezoelectric substrate 22, are dipped in a naphthalene solution heated up to 40-80 deg.C to stick naphthalene 24 to the outside of the piezoelectric substrate 22. Then, the piezoelectric substrate 22 having the stuck naphthalene is dipped in and taken out of twin pack thermosetting silicone rubber to form an elastic film 26 around the naphthalene. The whole body is heated to perform the setting of the silicone rubber 26 and the sublimation of the naphthalene. Lastly, a resin layer 28 is formed around the silicone rubber 26.
