Abstract:
A detection circuit includes a pyroelectric element; a first P-type transistor provided between an output node and a low-potential-side power node of the detection circuit, a detection signal being inputted from the pyroelectric element to a gate of the first P-type transistor; and a second P-type transistor provided between a high-potential-side power node and the output node, a gate of the second P-type transistor being set to a reference voltage.
