The inspection jig includes a rigid substrate, a flexible substrate connected to the rigid substrate, a contactor block for supporting a part of the flexible substrate in a state that the part of the flexible substrate is protruded with respect to the rigid substrate, a contactor provided on a protruding portion of the flexible substrate, and a spring probe supported by the contactor block, one end of which is in contact with a contact pad provided on a lower surface of the rigid substrate, and the other end of which protrudes from a protruding portion of the flexible substrate.
