A touch sensor unit installed on one of an opening provided in a vehicle and an opening and closing body configured to open and close the opening, the touch sensor unit comprising:

• a touch sensor having a sensor body;
• and
• a bracket configured to hold the touch sensor in a longitudinal direction of the sensor body and fixed to one of the opening and the opening and closing body, wherein
• one of the touch sensor and the bracket includes an inserting portion including a locking piece,
• an other of the touch sensor and the bracket includes a holding portion including a locking portion locked to the locking piece and configured to accommodate the inserting portion,
• one of the inserting portion and the holding portion is made of an elastomer having an elastic modulus lower than that of the other,
• the touch sensor includes the inserting portion made of an elastomer, and
• the bracket includes the holding portion,
• when a direction orthogonal to both an inserting direction of the inserting portion with respect to the holding portion and the longitudinal direction is defined as a width direction,
• the holding portion includes a bottom wall extending in the longitudinal direction and first and second side walls extending from both ends of the bottom wall in the width direction in a direction opposite to the inserting direction,
• the locking portion includes a plurality of first locking portions extending from a tip end portion of the first side wall toward the second side wall in a state of being spaced apart in the longitudinal direction, and a plurality of second locking portions extending from a tip end portion of the second side wall toward the first side wall in a state of being spaced apart in the longitudinal direction,
• the plurality of first locking portions and the plurality of second locking portions are positioned so as to face each other in the width direction, and
• the bottom wall includes a plurality of through holes in portions overlapping the plurality of first locking portions and the plurality of second locking portions in the inserting direction.
