The present invention provides a means for suppressing an occurrence of a ghost by enhancing diffraction efficiency of a holographic optical element having a volume hologram recording layer. The present invention is a holographic optical element including: a volume hologram recording layer containing a photopolymer; and at least one adjacent layer which is in contact with the volume hologram recording layer and contains a resin, wherein a diffraction grating is formed so as to extend from the volume hologram recording layer to the adjacent layer.

A window cover for an automobile integrally includes: a front sheet to cover an outer surface of an automobile windshield; and a pair of side sheets to cover outer surfaces of left and right front door glasses, respectively. The side sheets are fixed to a vehicle body by a fixing device. The device includes a plate-shaped tab fixed to a rear edge of each side sheet. The tab is fixed by being inserted into a clearance between a rear edge of each of the front door glasses and a front edge of a rear door glass of a rear door placed rearward of the rear edge. Accordingly, convenience is improved because the cover can be easily attached to the vehicle body with the front and rear doors remaining closed, and workability is not deteriorated because the cover is not twisted or entwined when the front doors are opened or closed.

Method for producing a lens array, which can prevent a weld from being formed in the peripheral part of a lens part and suppress increase of a work time of a transfer mold, and a molding mold. Since a master moldof a molding mold has a plurality of linear groove partssurrounding a plurality of cavity parts, resin hardly spreads to a corner partwhere the adjacent linear groove partsandintersect each other and it is possible to prevent portions of the resin which have run over toward the adjacent groove partsandfrom spreading so as to come close to each other and being brought into contact with each other to create a weld trapping air bubbles.

Disclosed is an image pickup device, by which cut resistance at the time of cutting a wafer lens is reduced, high production efficiency is maintained, and excellent optical characteristics are obtained. The image pickup device has a first lens block, a second lens block, a spacer, and a sensor unit. The side surface section of the first lens block, the side surface section of the second lens block, and the side surface section of the spacer are formed on the same plane. A lens cover that covers the first and the second lens blocks is provided in a step formed by respective side surface sections of the first lens block, the second lens block and the spacer, and the side surface section of the sensor unit.

There is provided a mudguard mounting structure, superior in versatility and capable of reducing the number of steps for mounting. The present invention is a structure for mounting a mudguard on a rear bumper of a vehicle, in which a mounting member is used to mount the mudguard on the rear bumper, said mounting member comprising a clamping portion on one side thereof for clamping an end portion of the rear bumper, and a mounting portion on which the mudguard is mounted on an other side. The mounting member can be mounted on the rear bumper by allowing the clamping portion to clamp the aforementioned end portion, thereby reducing the number of parts and steps for mounting, and costs. Since the mounting member excels in versatility, costs can be further reduced. An engagement portion for engaging the rear bumper is provided on an inner surface of the clamping portion.
