1. An inspection jig attached to an inspection processing portion of a board inspection apparatus that inspects an electric circuit included in a board to be inspected, the inspection jig comprising:
a first board on which a signal is detected by the inspection processing portion;
a probe unit including a probe that comes into contact with the board to be inspected;
a second board having one surface facing the first board, located in parallel with the first board in a thickness direction of the first board, and electrically connected to the probe;
an electrical connection portion located between the first board and the second board in the thickness direction and electrically connecting the first board and the second board; and
a board holding portion that holds the second board in a state of being in parallel with the first board in the thickness direction and holds the probe unit on a side opposite to a first board side,
wherein the board holding portion includes:
a plate-shaped first holding plate located on a probe unit side of the second board; and
a holding plate support portion that positions the first holding plate at a position where the first holding plate is in parallel with the first board in the thickness direction, and
the board holding portion holds the second board in a state where the first board and the second board are electrically connected via the electrical connection portion by sandwiching the electrical connection portion in the thickness direction between the first board and the second board.
