PROBLEM TO BE SOLVED: To realize an operation input device which allows use of touch without spoiling an operational feeling of a touch pad.SOLUTION: An operation input device comprises: a touch pad 10 that includes an operation plate 11, on a surface of which an operation surface 11a is formed, and senses an object to be sensed in contact with or in proximity to the operation surface 11a to receive input corresponding to a position of the sensed object; a hole portion 12 provided to penetrate through the operation plate 11; a protrusion member 20 inserted into the hole portion 12; and a drive mechanism provided on a back surface side with respect to the operation plate 11 and capable of causing advancing/retracting operation of the protrusion member 20 along a direction intersecting the operation surface 11a between a first state in which a distal end portion of the protrusion member 20 is above the operation surface 11a and a second state in which the distal end portion is not above the operation surface 11a. |
