A mass spectrometer is provided that restrains the signal intensity of an MS / MS spectrum from decreasing according to the secondary dissociation of a primary fragment ion generated by a photodissociation. An excitation laser light for causing a photodissociation is irradiated to the trapping space A in the ion trap 1. At the same time, an excitation signal that does not excite a precursor ion but excites fragment ions is applied to the end cap electrodes 12 and 13.
