1. A sample support body used for ionizing a component of a sample, the sample support body comprising:
a substrate;
a porous layer provided on the substrate and having a front surface on a side opposite to the substrate; and
a partition portion partitioning the front surface into a first region and a second region, wherein
the porous layer includes a main body layer having a plurality of holes opening to the front surface, and
the partition portion includes a partition groove formed on the front surface so as to pass between the first region and the second region.
