Provided are an electric power generating apparatus for a movement type equipment and a self-generation system having the same. The electric power generating apparatus for a movement type equipment includes: a piezoelectric beam having an end fixed to a movement type equipment and other end with a mass; and a rectifier unit for rectifying and storing electric energy generated due to deformation of the piezoelectric beam. The self-generation system includes: a movement type equipment; and an electric power generating apparatus for a movement type equipment including a piezoelectric beam having an end fixed to a movement type equipment and other end with a mass, and a rectifier unit for rectifying and storing electric energy generated due to deformation of the piezoelectric beam. According to the electric power generating apparatus for the movement type equipment and the self-generation system having the same, since external movement is converted into vibration perpendicular to an electric beam using elasticity of the electric beam and load applied to an end of the beam, continuous vibration is induced to the piezoelectric beam. Also, high energy conversion efficiency can be obtained by using resonance.
