<P>PROBLEM TO BE SOLVED: To provide an energization pressure sensor that can measure a pressurizing force by directly receiving it from a welding electrode of a resistance welding machine and that can simultaneously measure electric current and voltage. Ž<P>SOLUTION: The energization pressure sensor includes an energizing block 19 that makes an electric current flow by receiving electricity supply from welding electrodes 2, 3 and that elastically deforms by receiving a pressurizing force from the welding electrodes 2, 3, with a gap G made to fluctuate, and also includes a pressure sensor 25 that is mounted in the gap G of the energizing block 19 and that measures the pressurizing force by directly receiving it from the welding electrodes 2, 3. In the energization pressure sensor, when R1 denotes the resistance value of the gap G of the energizing block 19 and R2 denotes the resistance value between the energizing block 19 and the pressure sensor 25, R1<R2 is satisfied.
