PROBLEM TO BE SOLVED: To provide a drug useful for photoimmunotherapy. A complex containing an antibody molecule, particles having an average particle diameter of 100 nm or less, and a light-sensitive site. In the complex, the particles having an average particle diameter of 100 nm or less are bound to the antibody molecule, and the antibody molecule and at least one of the particles are bound to the light-sensitive site. The light-sensitive site is a site whose hydrophobicity is increased by irradiation with a light beam having a wavelength of 500 to 900 nm or a site containing a phthalocyanine skeleton.
