<p>PROBLEM TO BE SOLVED: To provide an accommodation case which simplifies accommodating operation of a piezoelectric transformer device, and which can be readily mounted on a circuit substrate. SOLUTION: The end surfaces of an accommodation case 1 are provided with mounting terminals 4a, 5a and 6. These mounting terminals play a role of mounting a piezoelectric device on a circuit substrate of the accommodation case 1, and a role of lead electrodes of external electrodes and output electrodes of the device accommodated in the case. The piezoelectric device is fixed inside the accommodation case 1 by lead electrodes 4, 5 which are, respectively, integrated with the mounting terminals 4a, 5a and protrusions 2 and 3.</p> |
