1. A position detection device comprising:
a sensor including a detection unit configured to output a signal corresponding to a change in a position of an object, which is to be detected, and a resin portion covering the detection unit; and
a cover formed of a resin, which has a linear expansion coefficient different from a linear expansion coefficient of the resin portion, to cover a part of the resin portion such that the resin portion protrudes, wherein
the resin portion has
a protruding surface facing a direction in which the resin portion protrudes and
a side surface connected to the protruding surface,
the cover has
a covering surface facing the direction in which the resin portion protrudes,
an inclined surface intersecting with each of the covering surface and the side surface to be connected to each of the covering surface and the side surface, and
a projecting portion projecting in the direction in which the resin portion protrudes,
the projecting portion is connected to each of the side surface and the inclined surface,
the side surface is a first side surface,
the inclined surface is a first inclined surface,
the resin portion has
a second side surface connected to each of the protruding surface and the first side surface and
a corner portion that is a boundary portion between the first side surface and the second side surface,
the cover further has a second inclined surface intersecting with each of the covering surface and the second side surface to be connected to each of the covering surface and the second side surface, and
the projecting portion is connected to each of the first side surface, the second side surface, the corner portion, the first inclined surface, and the second inclined surface.
