Abstract
A detection method of detecting a target substance, the method includes exciting the target substance by irradiating an atmosphere of a detection space with light having a first wavelength that excites the target substance from a ground state to an excited state on the basis of the energy level structure of the target substance; ionizing the target substance by irradiating the atmosphere of the detection space with light having a second wavelength that excites the target substance from the excited state to an energy state substantially equal to or higher than a vacuum level; making the ionized target substance adsorb to a detector by electric field acceleration; and detecting the amount of adsorption of the target substance.
