Abstract
A crystal oscillation device includes a crystal oscillator including a package with first connecting electrodes provided on a flat bottom surface mounted on a flat, thin circuit board. Circuit components and second connecting electrodes provided in one-to-one correspondence with the first connecting electrodes are mounted on one principal surface of the circuit board. The crystal oscillator is supported by top surfaces of a transistor and a varicap diode that are the highest among the circuit components mounted on the circuit board. The crystal oscillator and the circuit board are electrically connected with solder provided between the first and second connecting electrodes. The solder also attracts the crystal oscillator toward the circuit board.
