摘要： In an oscillator of the invention, the shape and position of each chip and wiring between the chips are optimally designed. Since a SAW element and an IC which have satisfactory reliability are arranged in the same package, the oscillator is not greatly influenced by external electromagnetic induction, is not unstably oscillated, and has satisfactory reliability.
