Abstract

Provided are an ion source and a mass spectrometer that reduce a dead volume of the connecting part of a pipe to a capillary. An ion source has a capillary and a pipe. The capillary has a large-diameter part that forms a capillary upstream-side end face on an upstream side. The large-diameter part has a large-diameter part downstream side face on a downstream side. The pipe has a pipe downstream end face on the downstream side. A capillary retaining unit has a hole through which the capillary downstream-side end face is passable and a face on which the large-diameter part downstream side face is installable. The ion source includes a pipe retaining unit that retains the pipe. The capillary retaining unit and the pipe retaining unit are disposed such that the capillary upstream-side end face contacts the pipe downstream end face to connect the capillary to the pipe.
