An image pickup apparatus for endoscope includes: an imager, an optical device, an optical module on which the optical device is mounted, an optical fiber optically coupled with the optical device, a ferrule having an insertion hole into which the optical fiber is inserted, and a wiring board including a first rigid board, a second rigid board and a flexible intermediate board. The ferrule is fixed to the second rigid board or a first principal surface of the optical module. A first side surface of the optical module is glued to the first rigid board, and the first principal surface is glued to the second rigid board.

An optical transmission module includes a substrate having an opening portion; an optical element closing an opening on the lower surface side of the substrate and converting an electric signal into an optical signal or the optical signal into the electric signal; an optical fiber transmitting the optical signal; a ferrule closing an opening on the upper surface side of the substrate and having an optical fiber insertion hole; and a resin filled into a space surrounded at least by the substrate, the optical element, the ferrule, and a distal end of the optical fiber, wherein the ferrule has a resin filling hole spaced apart from the optical fiber insertion hole to fill the space with the resin, and an angle formed by an axis of the optical fiber insertion hole and an axis of the resin filling hole is equal to or more than 0&#xb0; and less than 90&#xb0;.

Optical transmission module, imaging apparatus, and optical transmission module structure

A wireless power supply apparatus for a capsule-type endoscope has three sets of coils that generate a magnetic field in directions that are orthogonal to each other, a gravity sensor that detects a gravitational direction, a coil selection section that selects a coil that generates a magnetic field in a gravitational direction that is detected by the gravity sensor, and a drive section that applies a current to the coil that the coil selection section selects.
