A detecting apparatus for checking shape, size and/or position of a hole of a workpiece, includes a platform for supporting the workpiece, a detecting board, which includes a detecting unit, movably set above the platform, an electrical source, a processor, and an indicator. The source, the unit, and the workpiece make up a circuit connected to the processor. When the board is moved to the workpiece, and the unit enters the hole without touching the workpiece the circuit will remain open, and the processor will control the indicator to indicate that the hole is eligible. If the detecting unit touches the workpiece, the circuit closes, and the processor will control the indicator to indicate that the hole is ineligible. An end of the unit that enters the hole is radially deformable. The apparatus improves detecting efficiency and accuracy, and is suitable for use in mass production.
