Photoelectric sensor comprising at least one of a light projecting side light guide part and a light receiving side light guide part extends with at least a part thereof inclined with respect to a predetermined direction

A photoelectric sensor, comprising:

• a case comprising a first case member and a second case member disposed opposite to the first case member, wherein a housing space is formed between the first case member and the second case member;
• a base board disposed in the housing space and mounted with a light projecting part for emitting light and a light receiving part for receiving light, which are separated from each other;
• a light guide member disposed in the housing space and comprising a light projecting side light guide part guiding light from the light projecting part to outside of the case, and a light receiving side light guide part guiding light from the outside of the case to the light receiving part;
• and
• a light shielding member disposed in the housing space, defining a positional relationship between the base board and the light guide member, and shielding light between the light projecting part and the light receiving part,
• wherein one of the light projecting side light guide part and the light receiving side light guide part extends in a predetermined direction,
• the other one of the light projecting side light guide part and the light receiving side light guide part extends with at least a part thereof inclined with respect to the predetermined direction, and
• the light shielding member comprises a fitting part, into which the one of the light projecting side light guide part and the light receiving side light guide part fits in the predetermined direction, and a contact part that is in contact with the base board in the predetermined direction.
