PROBLEM TO BE SOLVED: To provide a power detection device capable of reducing the possibility that an accommodation part (package) in which a piezoelectric element is accommodated will break down even when subjected to a repetitive external force, and a robot.SOLUTION: A power detection device 1 comprises a first base part 2, a second base part 3, and a pressure detection part 6 provided between the first base part 2 and the second base part 3 and including a piezoelectric element 10 for outputting a signal in accordance with an external force. The pressure detection part 6 has a first member 61 having a portion in contact with the first base part 2, a second member 62 having a portion in contact with the second base part 3, and a third member 67 for connecting the first member 61 and the second member 62. First modulus of longitudinal elasticity of at least part of the first member 61 is lower than third modulus of longitudinal elasticity of the third member 67, and second modulus of longitudinal elasticity of at least part of the second member 62 is lower than the third modulus of longitudinal elasticity of the third member 67. |
