PURPOSE:To improve mounting density by forming conductive films at the corners of a plate-like piezo-electric oscillator and mounting the oscillator perpendicularly on a base plate. CONSTITUTION:A resonator, a filter, a discriminator or the like can be applied as a piezo-electric oscillation unit 101. The piezo-electric oscillator unit 101 is sandwiched by two insulating plates 11. Notched parts are formed at least at two portions of the insulating plates 11 such as corner parts to be coated with conductive films. The number of the notched parts required is equivalent to the number of electrodes included in the piezo-electric oscillator unit 101. If the notched parts are required on the three positions, it is sufficient to provided additionally are notched part on the central part of the insulating plates 11. When the piezo-electric oscillator unit 101 formed by said method is soldered on the base plate together with other parts, the plate-like chip part is perpendicularly formed on the base plate so that the area occupied by the plate-like chip part is reduced. |
