Provided are a wideband ultrasonic probe for a photoacoustic image and an ultrasound image. The wideband ultrasonic probe includes a first ultrasonic transducer array and a second ultrasonic transducer array that are disposed on a substrate and a laser apparatus that comprises a laser irradiator configured to irradiate a laser light onto a diagnosis object, wherein the first ultrasonic transducer array receives a first ultrasonic wave which is generated from the diagnosis object on which the laser light is irradiated, and the second ultrasonic transducer array transmits a high frequency bandwidth ultrasonic wave toward the diagnosis object and receives a second ultrasonic wave that is reflected by the diagnosis object.
