1. A heat flux sensor that detects heat flux comprising:
a main body that detects heat flux, having a first surface on a first surface side of the main body and a second surface on an opposite side of the main body from the first surface side, the first surface having an uneven shape with a plurality of concave portions and a plurality of convex portions; and
a flattening member disposed on the first surface side of the main body, made of a material having a higher thermal conductivity than air, for flattening an outer surface of the main body on the first surface side; wherein
the flattening member fills in at least one of the plurality of concave portions;
a surface of the flattening member constitutes at least part of the outer surface; and
a degree of flatness of the outer surface is higher than a degree of flatness of the first surface;
the main body is made at least of a resin;
the flattening member is made of a material having higher thermal conductivity than the resin and has a plate-like member of plate-like form;
the plate-like member has one surface and an other surface on an opposite side of the plate-like member from the one surface, and the one surface is stacked on the first surface side of the main body facing the first surface;
parts of the plate-like member fill in the concave portions; and
the other surface of the plate-like member constitutes the outer surface.
