PROBLEM TO BE SOLVED: To provide an oscillation circuit capable of reducing the possibility of erroneously switching operation mode, an oscillator, an electronic apparatus, a moving vehicle and a control method of the oscillator.SOLUTION: An oscillation circuit 1 includes: a power supply detection section 10 that detects the state of the power supply; a determination section 20 that determines the input state of a predetermined signal; and a control section 30 that, when the determination section 20 determines that an input of a predetermined signal is detected within a predetermined time from the power supply detection section 10 detects the turning ON of the power supply, selects a first operation mode, and when other case, the control section 30 selects a second operation mode.SELECTED DRAWING: Figure 1 【課題】誤って動作モードが切り替わる可能性を低減できる、発振回路、発振器、電子機器、移動体及び発振器の制御方法を提供すること。【解決手段】発振回路１は、電源の投入の状態を検出する電源検出部１０と、所定信号の入力の状態を判定する判定部２０と、電源検出部１０が電源の投入を検出してから所定時間以内に、判定部２０が所定信号の入力を検出したと判定した場合には第１動作モードを選択し、他の場合には第２動作モードを選択する制御部３０と、を含む。【選択図】図１
