1. A perspiration mapping patch configured to be attached to skin of a user to absorb sweat and defining a stacking direction and a plane direction orthogonal to the stacking direction, the perspiration mapping patch comprising:
a sweat absorbing layer in which a plurality of opening units is arranged;
a first support layer which is stacked on a first surface of the sweat absorbing layer along the stacking direction and includes an opening opened to correspond to each of the plurality of opening units; and
a second support layer stacked on a second surface facing an opposite side of the first surface of the sweat absorbing layer,
wherein each of the plurality of opening units comprises a first portion that overlaps the opening of the first support layer along the stacking direction and a second portion that does not overlap the opening of the first support layer along the stacking direction, and
wherein each of the openings of the first support layer comprises a third portion that does not overlap the opening units of the sweat absorbing layer along the stacking direction.
