A class D amplifier circuit for generating a pulse signal whose pulse width is modulated in response to an input signal, the class D amplifier circuit includes first to fifth switching elements, a first capacitance element and a control section. The control section controls transition between a conduction state and a non-conduction state of each of the first to fifth switching elements to control a current direction flowing into a load having a first end electrically connected to the output end and a second end set to the reference potential, so that the current flows from the first end of the load to the second end of the load at a first timing and the current flows from the second end of the load to the first end of the load at a second timing.
