Claim 12:
13. The sensor according to claim 10, wherein
the support member includes a protruding surface protruding in a direction away from the top surface of the substrate and including the at least one inclined surface,
the protruding surface includes an upper end portion farthest from the top surface of the substrate, and also includes a curved surface portion including the upper end portion of the protruding surface and protruding in the direction away from the top surface of the substrate,
the curved surface portion includes a first portion including the upper end portion of the protruding surface, and a second portion continuous with the first portion at a position away from the upper end portion of the protruding surface, and
when a shape of the protruding surface in a cross section perpendicular to the top surface of the substrate is regarded as a function Z having as a variable a position on a virtual straight line that is parallel to each of the cross section and the top surface of the substrate, a mean value of an absolute value of a second derivative Z″ of the function Z corresponding to the first portion is smaller than a mean value of an absolute value of the second derivative Z″ of the function Z corresponding to the second portion.
