摘要： The present invention provides a probe apparatus, which comprises a signal transmission device, a probe, and a bottom fixing device. The signal transmission device includes a first transmission part and a second transmission part. An end of the probe is connected electrically below the second transmission part. The bottom fixing device is disposed below the signal transmission device. An end of the bottom fixing device includes a first penetrating hole and a first recess is disposed below the end. The probe passes through the first penetrating hole of the bottom fixing device. The probe is located in the first recess. The bottom fixing device reinforces the mechanical strength of the signal transmission device so that the width of the signal transmission device can be reduced. Thereby, the benefit of high-density arrangement of the probe apparatus can be achieved.
