To provide a medical energy irradiation apparatus which permits easy and accurate establishment of a site of tissues of a living body targeted for irradiation with energy, when doctors use the medical energy irradiation apparatus to perform a cure for a prostatic hyperplasia or the like. The doctors insert an applicatorof the medical energy irradiation apparatus to an urinary bladderand fix an endoscopenear to an entrance of an urethra. In this arrangement, when observing with the endoscope (), a seminal colliculasobserved through a side-observation windowis observed toward a lower part of an observed image (schematic diagram) displayed on a display unit, and a positioning markerin an interior of the applicator is observed toward an upper part of an observed image. The doctors can accurately determine a position to be irradiated with laser light from positions of the seminal colliculasand the positioning markerobserved, and a direction of irradiation with laser light from a position of a direction marker, respectively.
