PROBLEM TO BE SOLVED: To provide a normally closed plunger type touch sensor which can solve a problem in a conventional one that a high precision and an outer diameter as thin and short as possible is demanded for down-sizing a mounting machine and for easy mounting work in a small space. SOLUTION: For realizing a small and short diameter simultaneously, a groove is provided on an outer circumference of an insulation cylinder which houses the contact point portion as an electric conducting means between a contact point portion and a rear terminal, and an electric conducting material of a small cross section is housed in the groove.
