Problem to be solved: to provide a package and a measurement sensor suitable for measuring a shallow portion of an object to be measured.The package 10 of the present invention comprises a plate-like substrate 12 having a plurality of dielectric layers laminated and having a first surface 21 and a second surface 22 in the front and rear relationship, a first partition 23 provided in the first surface 21 and accommodating the light emitting element 14, and is disposed on the first surface 21 and the light receiving element 15 A second recessed recess 24 for accommodating the second recess 26, which is disposed in the first confine recess 23, and is disposed on the first and second concave recesses 23, 23, and a second bottom surface 27 provided on the second recessed recess 24 to place the light receiving element. The first bottom surface 26 is inclined in a direction facing the first bottom surface 26 and the second bottom surface 27. That is, the first bottom surface 26 is non parallel to the first surface 21, and the second bottom surface 27 is parallel to the first surface 21.Diagram【課題】被計測物の浅い部分の計測に適したパッケージ及び計測センサを提供する。【解決手段】本発明のパッケージ10は、複数の誘電体層が積層されて成り、表裏関係にある第一面21及び第二面22を有する板状の基体12と、第一面21に設けられ、発光素子14を収容する第一収容凹部23と、第一面21に設けられ、受光素子15を収容する第二収容凹部24と、第一収容凹部23に設けられ、発光素子14を載置する第一底面26と、第二収容凹部24に設けられ、受光素子15を載置する第二底面27と、を備えている。そして、第一底面26が、第一底面26と第二底面27とが互いに向き合う方向に傾斜している。すなわち、第一底面26が第一面21に非平行であり、第二底面27が第一面21に平行である。【選択図】図1
