To provide an explosion-proof electric apparatus capable of attaining miniaturization and lightness of the apparatus and sufficiently supplying power to an intrinsically-safe circuit by reducing wiring inductance and capacitance between the intrinsically-safe circuit and an intrinsically-safe related circuit at a negligible state.
A intrinsically-safe circuit section 1 for internally storing an LED board 11 and an intrinsically-safe related circuit section 2 with a resin filled explosion-proof structure for internally storing cables 25, a power source 21, and the intrinsically-safe circuit 22 are detachably arranged in the explosion-proof electric apparatus. A first connection section 15 and a second connection section 23 are exposed to respective attaching and detaching surfaces of the intrinsically-safe circuit section 1 and the intrinsically-safe related circuit section 2. The first connection section 15 and the second connection section 23 are electrically connected each other, and the intrinsically-safe circuit section 1 and the intrinsically-safe related circuit section 2 are also combined.
