Further, the first connection section 231 and the first extension section 232 can form the first high-frequency oscillator arm 23 into an L-shaped oscillator structure, and the second connection section 331 and the second extension section 332 can form the second high-frequency oscillator arm 33 into an L-shaped oscillator structure.
