An endoscope includes a single lens that has a square exterior shape in a direction perpendicular to an optical axis, an image sensor that has an square exterior shape which is same as the exterior shape of the single lens, in the direction perpendicular to the optical axis, a sensor cover that has an exterior shape which is same as the exterior shape of the single lens, in the direction perpendicular to the optical axis; and a bonding resin portion that fixes the sensor cover to the single lens, The single lens is a lens which is formed in a prismatic shape. The single lens has first surface on an imaging subject side that has a plane, and has second surface on an imaging side that has a convex surface.

Endoscope

An endoscope which promotes downsizing and cost reduction, and a manufacturing method of an endoscope are provided. For this reason, in an endoscope, a lens unit containing a lens in a lens tube, an image capturing element of which an image capturing surface is covered with element cover glass, and an adhesive resin fixing the lens unit of which an optical axis of the lens is coincident with the center of the image capturing surface to the element cover glass with a separation portion are disposed.

A chip-type light-emitting semiconductor device includes: a substratea blue LEDmounted on the substrateand a luminescent layermade of a mixture of yellow/yellowish phosphor particlesand a base material(translucent resin). The yellow/yellowish phosphor particlesis a silicate phosphor which absorbs blue light emitted by the blue LEDto emit a fluorescence having a main emission peak in the wavelength range from 550 nm to 600 nm, inclusive, and which contains, as a main component, a compound expressed by the chemical formula: (SrBaCaEu)SiO(0&#x2264;a1&#x2264;0.3, 0&#x2264;b1&#x2264;0.8 and 0&#x3c;x&#x3c;1). The silicate phosphor particles disperse substantially evenly in the resin easily. As a result, excellent white light is obtained.
