Electronic apparatus, non-contact switch, and photoelectric sensor

An electronic apparatus comprising:

• a case;
• a plurality of substrates disposed in the case, each of the plurality of substrates being mounted with an electronic component thereon;
• a thermoplastic hot-melt resin filled in the case;
• a fluid branch member;
• and
• a substrate holding part for fixing the plurality of substrates to predetermined positions in the case,
• wherein the fluid branch member is fixed to the substrate holding part,
• wherein the inside of the case is divided by the plurality of substrates into a plurality of spaces,
• wherein the plurality of spaces comprises spaces between the case and one or more of the plurality of substrates and spaces between the plurality of substrates, and are filled with the thermoplastic hot-melt resin, and
• wherein the plurality of substrates comprises at least two substrates that are disposed parallel to each other along a first direction,
• the substrate holding part is located in a space between the two substrates, and
• the fluid branch member is fixed below the holding part and the two substrates in the first direction,
• wherein the fluid branch member is provided with:
• an opening as an inlet for filling the thermoplastic hot-melt resin into the case, and
• a flow path part for branching the thermoplastic hot-melt resin into multiple parts and guiding the thermoplastic hot-melt resin from the opening to the plurality of spaces.
