发明名称 OPTICAL DETECTION UNIT AND BIOLOGICAL INFORMATION DETECTION DEVICE
摘要 An optical detection unit includes a light emitting portion 150 that emits light toward a target object, a light receiving portion 140 that receives light from the target object, and a light blocking member 70 that blocks light from being incident to at least the light receiving portion 140. The light blocking member 70 includes a light blocking wall 100 that is formed by performing sheet metal processing on a metal, and is provided between the light emitting portion 150 and the light receiving portion 140 so as to block light from the light emitting portion 150 from being incident to the light receiving portion 140. The light blocking wall 100 is formed of a first metal surface 71 of the light blocking member 70.

主权项 1. An optical detection unit comprising: a light emitting portion that emits light toward a target object; a light receiving portion that receives light from the target object; and a light blocking member that includes a light blocking wall which is provided at least between the light emitting portion and the light receiving portion, wherein the light blocking wall is made of a metal, wherein the light blocking wall is formed of a first metal surface of the light blocking member, wherein the light blocking member is provided with a second metal surface and a third metal surface that are provided in a direction perpendicular to the first metal surface, wherein a first end surface of the first metal surface protrudes further toward one side than an end surface of the second metal surface in a front view in which the first metal surface is viewed from the light emitting portion side, and wherein a second end surface of the first metal surface opposing the first end surface protrudes further toward the other side which is different from one side than an end surface of the third metal surface in the front view.
