Abstract: A touch detection device has a sensing unit that includes a contact portion which comes into contact with an object, a vibration excitation element that vibrates the contact portion, a detection circuit that includes a drive circuit and a contact determination circuit, and an electrical wire that connects the vibration excitation element and the detection circuit, and is covered with a covering material. The vibration excitation element is covered with a potting layer made of resin through a predetermined internal space. While being inserted into the potting layer, the electrical wire has an end connected to the vibration excitation element, and an insertion portion inserted into the potting layer includes a non-covering portion formed by peeling of the covering material.
