PROBLEM TO BE SOLVED: To provide a pressure sensor whose resistance value can be smoothly changed to a load in a load region where the load is relatively small and which can detect even in a load region where the load is relatively heavy, and to provide a method of manufacturing the pressure sensor. SOLUTION: This pressure sensor for sensing a load includes an uneven layer 6 made of insulating resin containing non-conductive particles 6a formed on a surface of a second substrate 3, and a resistor layer 7 containing at least carbon powder formed on a surface of the uneven layer 6. The total thickness of the film thickness of the uneven layer 6 and film thickness of the resistor layer 7 between the non-conductive particles 6a are smaller than the particle size of the non-conductive particles 6a contained in the uneven layer. At least the resistor layer 7 is formed on the non-conductive particles 6a and between the non-conductive particles 6a. COPYRIGHT: (C)2011,JPO&INPIT
