A terminal module M1 is to be accommodated into an outer housing 30, and includes male terminals 20 to be connected to ends of signal wires 11, a first terminal holding member 61 including accommodation recesses 78 for accommodating the terminals 20 inserted in a direction intersecting an extending direction of the terminals 20 with tip parts 21 of the terminals 20 projecting, and a second terminal holding member 65 to be assembled with the first terminal holding member 61. The second terminal holding member 65 is relatively movable toward ends of the signal wires 11 from a terminal tip protection position where the second terminal holding member 65 covers tip parts 21 of the terminals 20 projecting from the first terminal holding member 61.
