A filter element includes a first glass substrate having a pair of parallel surfaces and a band pass filter arranged on one of the parallel surfaces, a pair of single-crystal substrates (Si wafers) each including a primary surface formed with a depression having an inclined surface with respect to the primary surface occupying at least one half of the opening of the depression, and a second glass substrate having an optical element. The primary surfaces of the single-crystal substrate pair are bonded to a pair of the surfaces of the glass substrate. The depressions are faced through the glass substrate and surround the band pass filter. By this configuration, the filter element can be mass produced with a high accuracy and a low cost by the wafer-level process.

In a laser welding method, detachment is suppressed and dislocation of an optical component is reduced by improving adhesiveness of an interface of a welded part to thereby improve yield and reliability of an optical pickup device. A manufacturing method of an optical pickup device includes: a step of bringing the optical component into contact with the holding member; a step of irradiating laser light; and a step of melting the holding member through the irradiation to weld the holding member to the optical component, wherein before the laser light is irradiated, surface roughness of a portion of the optical component to be welded is greater than surface roughness of the holding member in contact with the portion, whereby the melted holding member enters into an uneven part on a front surface of the optical component, improving adhesion strength.

According to one embodiment, an electronic apparatus comprises a storage module, a location measuring module, a communication module, and a navigation image generating module. The storage module stores image data corresponding to respective symbols, and data of simplified diagram templates in each of which positions are set on an image showing a shape of a road, symbols being placed at the respective positions. The location measuring module measures a current location. The communication module transmits the current location to an external communication apparatus and receives navigation information on a navigation point corresponding to the current location, the navigation information including a simplified diagram template identification number, symbol identification numbers, and position specification numbers. The navigation image generating module generates the navigation image by reading the simplified diagram template and the image data of the symbols, and placing the image data at positions on the simplified diagram template.

To ensure required adhesion even when a pipe of a piping module collides with a temporary material during transport and achieve easier dismantling, the following measure is taken: the temporary material is fixed on a support rack to prevent the piping module placed on the support rack from largely displaced during conveyance and after the conveyance of the piping module, the temporary material is removed from the support rack. In this method, the following measures are taken: at the step of fixing the temporary material to the support rack, the temporary material is bonded to the support rack with the piping module set therein using adhesive; and at the step of removing the temporary material from the support rack after the conveyance of the piping module, the temporary material bonded to the support rack with the adhesive is peeled off from the support rack with heat applied thereto.
