PROBLEM TO BE SOLVED: To provide a dry type load test device for suppressing spark occurrence in a switching member even when it is installed outdoors or the like for a long time. SOLUTION: The dry type load test device includes a resistance body for high voltage load test where a plurality of slender resistance elements r<SB>i</SB>are arranged at intervals horizontally and perpendicularly and are interconnected in series horizontally, a plurality of switching members SWb<SB>ij</SB>, a plurality of electric conduction members Ca<SB>j</SB>and Cb<SB>j</SB>between assemblies, and a switch for high voltage (vacuum circuit breaker) for connecting some of the plurality of electric conduction members Ca<SB>j</SB>and Cb<SB>j</SB>between assemblies to a power supply (three-phase alternating-current generator). The switching members SWb<SB>ij</SB>have a sealed case body 69 that is filled with inert gas and includes a pair of fixed contacts (contact parts) connected to a pair of terminals Pa and Pb, a movable contact M conducting the pair of fixed contacts, and a driving means (solenoid) for driving the movable contact.
