An electronic type torsional wrench includes a handle, a force applying stem, a drive shank, and a pressure sensor. The pressure sensor includes a base member connected with the force applying stem, and a detecting member connected with the drive shank. In such a manner, when the relative pressure is formed between the force applying stem and the drive shank, the pressure sensor detects pressure values which are converted into torsion reading values by the converting unit, and the torsion reading values are displayed by the display monitor. Thus, the torsion reading values can be detected accurately, and the operation of the torsional wrench is convenient.
