PROBLEM TO BE SOLVED: To provide test equipment enabling a test of a light-receiving amplifier circuit of a smoke sensor by using a substrate single body alone without using complicated test equipment through the similar movement to actual movement. SOLUTION: This test equipment has a transistor having a collector connected with a cathode of a light emitting element for the test equipment, an inverter connected with an emitter of the transistor and having an output terminal connected with light emitting current limiting resistance for controlling the current flowing in the light emitting element for the test equipment and a base of the transistor through the resistance, a first probe connected with an input terminal of the inverter, a second probe connected with the first probe through the resistance, a light receiving element for the test equipment for receiving the light radiated by the light emitting element for the test equipment, a third probe connected with a cathode of the light receiving element for the test equipment, and a fourth probe connected with an anode of the light receiving element for the test equipment.
