PROBLEM TO BE SOLVED: To provide a reliable temperature compensating crystal oscillator for surface mounting that is specially suitable for reduced height, and has improved productivity. SOLUTION: In the temperature compensating crystal oscillator for surface mounting, a flat terminal plate having a plurality of lead terminals is provided, IC chips are arranged at the other-surface side of the flat terminal plate for directly connecting each lead terminal to a plurality of terminal electrodes of the IC chip, a crystal oscillator is arranged at the one surface side of the flat terminal plate, at the same time, the lead terminal connected to the crystal terminal electrode of the IC chip is directly connected to the mounting electrode of the crystal oscillator for resin-molding the IC chips, the lead terminal connected to the power supply, output, and terminal electrode for grounding of the IC chips is used as a mounting terminal for surface mounting for bending from the side of the resin molding to the bottom surface, and the lead terminal connected to the temperature compensating mechanism of the IC chip for writing compensation data is bent to the side of the crystal oscillator.
