An imaging apparatus includes a flash light emitting portion moving between a housed position and a light emitting position, a biasing means for biasing the flash light emitting portion toward the light emitting position, a member to be locked moving with a movement of the flash light emitting portion, a locking means for locking the member to be locked in a state in which the flash light emitting portion exists at the housed position and suppressing change of the position of the flash light emitting portion, opposing a biasing force by the biasing means and a lock releasing means having an electromagnet and a moving portion, for releasing a locked state of the member to be locked by moving the moving portion in a direction apart from the electromagnet by applying electric current to the electromagnet and by allowing the locking means to pivot about an axis.
