PROBLEM TO BE SOLVED: To provide a face pressure sensor whose rigidity is high, whose deformation amount with reference to compression is small, which is resistant to heat, which is flexible and which can measure the distribution of a face pressure. SOLUTION: Strain gages are pasted on side faces in central parts of quadratic prism-shaped bodies whose central parts are constricted. On the other hand, the quadratic prism-shaped bodies in which through holes in the X-direction and the Y-direction are made in their head parts and their bottom parts are arranged in a matrix shape as unit load cells 1. Thin wires 21, 22, 31, 32 and the like are passed through the through holes. Thereby, this face pressure sensor is constituted. Fig. (a) shows an example in which 2×2 pieces of the unit load cells 1 are arranged. Fig. (b) shows an example in which 4×4 pieces of the unit load cells 1 are arranged. In this manner, the face pressure sensor is constituted in such a way that the unit load cells in a plurality, whose rigidity is high are arranged in the matrix shape and that they are connected to each other by the thin wires. As a result the unit load cells are provided individually with high rigidity, and their deformation amount is small. The unit load cells are flexible as a whole. As a result, it is possible to obtain an advantage that a face pressure and the distribution of the face pressure can be measured precisely. In addition, since the face pressure sensor is resistant to heat, it can deal with a temperature change.
