Abstract
Provided is a position sensor with which the difference between the spectral intensities, in the vertical and horizontal directions, of light propagating through a lattice core can be easily reduced. This position sensor is provided with: a substantially rectangular sheet-like optical waveguide (W) having a sheet-like core pattern member provided with a lattice section (2A) comprising a plurality of linear cores (2), and an outer peripheral section (2B) which extends from each of the cores (2) of the lattice section (2A), and which is disposed along the outer periphery of the lattice section (2A); two light-emission elements (4); and two light-reception elements (5). One end surface and another end surface of the core (2) of the outer peripheral section (2B) from which the vertical-direction cores (2) of the lattice section (2A) extend, and one end surface and another end surface of the core (2) of the outer peripheral section (2B) from which the horizontal-direction cores (2) of the lattice section (2A) extend are positioned at one side of the rectangular shape of the optical waveguide (W). The one end surfaces of the two cores (2) of the outer peripheral section (2B) respectively have one of the light-emission elements (4) connected thereto. The other end surfaces of the two cores (2) of the outer peripheral section (2B) respectively have one of the light-reception elements (5) connected thereto.
